Summary: Bismuth doped fiber (BDF) and bismuth/phosphosilicate co-doped fiber (BPDF) were fabricated using atomic layer deposition (ALD) combined with modified chemical vapor deposition (MCVD). The spectral characteristics of the fibers were experimentally studied, showing that BPDF has good excitation effect in the O band. A diode pumped BPDF amplifier with a gain over 20 dB from 1298-1348 nm (50 nm) was demonstrated, with a maximum gain of 30 dB observed at 1320 nm and a gain coefficient of around 0.5 dB/m. Simulation results also showed that BPDF has a stronger excited state and greater significance in the O-band compared to BDF, mainly due to the formation of bismuth-phosphorus active centers through phosphorus (P) doping. The high gain coefficient of the fiber is of great importance for the industrialization of O-band fiber amplifiers.

Summary: Sm3+ doped sodium germanate glasses with suitable composition and good luminescence thermal stability were synthesized using high temperature melt-quenching technique. The luminescence performance and optical transition properties of Sm3+ in the glasses were studied. The concentration dependent luminescence quenching of the (4)G(5/2) level of Sm3+ was found to be due to the electric dipole-dipole interaction among Sm3+. Temperature dependent luminescence characteristics and thermal quenching behavior were also investigated, showing excellent luminescence thermal stability.

Summary: In this study, a phosphor Ba3In(PO4)(3):Er/Yb was synthesized with high Yb3+ doping concentration, which exhibited wide color gamut up-conversion luminescence from red to green with temperature variation. Four modes of fluorescence thermometry were realized based on the ratio of fluorescence intensity, color coordinate shift, and fluorescence decay lifetime. The highest temperature sensitivity obtained was 0.977% K-1. By using Ba3In(PO4)(3):0.02Er(3+)/0.05Yb(3+) phosphor, temperature mapping on a smooth metal surface with multiple optical encryptions was demonstrated. The Ba3In(PO4)(3):Er/Yb phosphor is an excellent fluorescent material for thermal imaging and has great potential in temperature visualization measurement and optical encryption.

Summary: This study investigates the effects of alkoxy groups on the adsorption, dye aggregation, and charge recombination process in dye-sensitized solar cells. It is found that alkoxy chains can not only shield but also assist dye adsorption and inhibit charge recombination by covering the TiO2 surface effectively. The existence of alkyl chains can also inhibit dye aggregation and reduce intermolecular electron transfer. Additionally, the Ti-O interaction between the alkoxy group and the Ti atom at the surface contributes substantially to interface stability. These findings provide new insights for the rational design of high-performance sensitizers.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
