Xuejiao Wang, Xiaowen Feng, Maxim S. Molokeev, Huiling Zheng, Qiushi Wang, Chunyan Xu, Ji-Guang Li

Summary: In this study, broadband emissions from (Lu0.99-xGdxBi0.01)(2)WO6 phosphors were obtained and modulated by varying the Gd3+ content. The effects of Gd3+ doping on various properties were investigated, and it was found that the emission intensity of the broadband green emission was enhanced by 50% with 5 at% Gd3+ doping. The phase transition and the broadband red-NIR emission were observed at higher Gd3+ contents. The obtained phosphors were used to fabricate high color rendering index pc-WLED and LED devices emitting white light and NIR light simultaneously, as well as for night vision and noninvasive imaging applications.

Quantifying the surface modification induced by the argon cluster ion bombardment of KGd(WO4)2: Nd single crystal

N. G. Korobeishchikov, I. V. Nikolaev, V. V. Atuchin, I. P. Prosvirin, A. V. Kapishnikov, A. Tolstogouzov, D. J. Fu

Summary: The damage caused by gas cluster ion bombardment on the surface of inorganic single crystals is still unresolved. In this study, the influence of the kinetic energy per atom in the clusters (E/N) on the physicochemical structure of KGd(WO4)2:Nd single crystals was evaluated using XPS, Raman spectroscopy, and XRD techniques. The results showed that high-energy mode with E/N of about 100 eV provides sufficient sputtering efficiency, while low-energy mode with a few eV energy causes minimal surface damage. The subsurface crystal structure remained undamaged after cluster bombardment, but an unexpected increase in relative concentration of O atoms by 12% and depletion of K atoms by a factor of 2 was detected in the subsurface layer of KGd(WO4)2:Nd crystals. The surface sputtering features of inorganic single crystals at different E/N modes are discussed.

Shuifu Liu, Dawei Wen, Rongkai Du, Chunyan Jiang, Jun Chen, Junhao Li, Lei Zhou, Maxim S. S. Molokeev, Mingmei Wu

Summary: Artificial light fishing technology has a long history in marine fisheries. A new generation of fish-attracting lamps with a light source that has multi-color adjustable output is being developed. The study proposes a new method of crystal-site engineering using reducing atmospheres to develop Eu2+ doped single-phase phosphor with multi-excitation and multi-emission properties. By modulating the distribution ratio of Eu2+ at Ca2+ and Sr2+ sites in CaSrSiO4 (CSO), the CSO:Eu2+ phosphor can achieve multi-color output. This phosphor has the potential to be used in futuristic fish-attracting lamps that cover the spectral sensitivity of most marine fish species.

Summary: In this study, the formation, structural properties, and energy spectrum of self-assembled GaSb/AlP quantum dots (SAQDs) were investigated. The growth conditions for SAQDs were determined on both GaP and GaP/Si substrates. The relaxation of strain in SAQDs on GaP/Si substrates did not affect the luminescence efficiency, while the introduction of dislocations in GaP-based SAQDs led to a quenching of luminescence. The energy spectrum of GaP/Si-based SAQDs was found to be of type II with an indirect bandgap.

Daria M. Turgunalieva, Alena L. Stalinskaya, Ilya I. Kulakov, Galina P. Sagitullina, Victor V. Atuchin, Andrey V. Elyshev, Ivan V. Kulakov

Summary: The multicomponent reaction of 2-nitroacetophenone, acetaldehyde diethyl acetal, beta-dicarbonyl compound, and ammonium acetate in acetic acid solution yielded 4-methyl-substituted derivatives of previously undescribed 5-nitro-1,4-dihydropyridine. Oxidation of the obtained derivatives resulted in 2,4-dimethyl-5-nitropyridines. This study also introduced the use of acetaldehyde diethyl acetal as a source of acetaldehyde in the synthesis of unsymmetrical 1,4-dihydropyridines, which produced controlled synthesis of unsymmetrical 5-nitro-1,4-dihydropyridines. The proposed multicomponent approach allowed the synthesis of previously undescribed substituted 5(3)-nitropyridines.

Summary: Heavy-metal contaminants are a significant problem in agriculture, threatening food security due to their high toxicity and ability to accumulate in soils and crops. This study aims to develop a consortium of microorganisms isolated from technogenic sites to address soil restoration in agriculture. Promising strains capable of removing heavy metals were selected, and a consortium (Consortium D) consisting of Achromobacter denitrificans, Klebsiella oxytoca, and Rhizobium radiobacter was found to be the most effective. Consortium D demonstrated the ability to produce phytohormones and remove heavy metals from experimental media. Furthermore, the combined use of Trifolium pratense L. and Consortium D improved the efficiency of phytoremediation. Further research will focus on developing a biological product for land remediation in agriculture.

Effect of n- and p-Doping on Vacancy Formation in Cationic and Anionic Sublattices of (In,Al)As/AlAs and Al(Sb,As)/AlAs Heterostructures

Timur S. Shamirzaev, Victor V. Atuchin

Summary: The vacancy generation dynamics in doped semiconductor heterostructures with quantum dots (QD) formed in the cationic and anionic sublattices of AlAs is investigated. It is experimentally demonstrated that the vacancy-mediated high temperature diffusion is enhanced or suppressed depending on the location of QDs in the heterostructures. A model is developed to explain the doping effect on the vacancy generation dynamics. Additionally, the impact of nonuniform charge carrier spatial distribution on the vacancy generation and diffusion at high temperatures is revealed.

Study of AlN growth using AMEC Prismo HiT3 MOCVD reactor

Jianzheng Hu, Long Yan, Ning Zhou, Yao Chen, Xiaoni Yang, Lianqiao Yang, Shiping Guo

Summary: The effect and mechanism of carrier gas velocity, V/III ratio, and carrier gas velocity match on the growth rate of AlN were investigated in this study. The results showed that the growth rate of AlN initially increased with hydrogen flow rate, reached saturation, and then decreased monotonically. The turning point value depended on the equipment and process. By increasing the MO VM, the growth rate of AlN could be improved, but the uniformity deteriorated due to turbulence and loss of uniform boundary layer. High quality AlN films were successfully grown on nano-patterned sapphire substrates with improved crystalline quality and atomic smooth surfaces.
