Summary: The study focuses on the synthesis and characterization of CdSe quantum dots using the solvothermal method. CdSe quantum dots were prepared by adjusting the pH value from 5 to 10, with glacial acetic acid added dropwise. The TEM characterization revealed an average particle size of 9.65 nm. The average band gap was calculated as 3.25 eV using a Tauc plot. XRD confirmed an average crystallite size of 6.93 nm. The CdSe nanoparticles at pH 5 exhibited the fastest degradation of dye water, as confirmed by UV-visible spectrophotometer.

Summary: We investigated the structural, vibrational, morphological, and electronic properties of Nb substituted orthova-nadate LaV1-xNbxO4 samples prepared by the solid-state reaction method. The x-ray diffraction (XRD) analysis revealed the presence of three crystal structures with an increase in Nb5+ concentration. Raman spectroscopy and x-ray photoelectron spectroscopy (XPS) were employed to study the vibrational and electronic properties of all the samples, respectively. Our study provided insights into the evolution of the structural, morphological, and chemical features with Nb substitution in LaV1-xNbxO4 samples.

Summary: A method is developed to simultaneously excite upconverting nanoparticles (UCNPs) as luminescent thermometers and photocatalysts using a single near-infrared laser, allowing for the separation of the thermometry signal from the chemical reaction signal in the spectral domain. This method provides high-fidelity surface temperature measurements and offers a valuable tool for elucidating thermal contributions to plasmonic photocatalysis.

Summary: Anisotropic rare earth ion (RE3+) doped fluoride upconversion particles have great potential in various fields, and a facile strategy to synthesize the particles was developed in this study. By controlling the synthesis time, NaYF4: Yb, Gd, Er, and NaYF4: Yb, Gd, Tm upconversion nanorods were successfully synthesized via microwave synthesis route, and their optical properties were compared with those prepared via solvothermal technique. The phase and morphology of the particles were found to change with the increase in synthesis time. Surface modification of the particles transformed their hydrophobicity to hydrophilicity, and the surface modification route influenced the upconversion luminescence and solvent-dependent emission properties. Furthermore, the laser power dependent studies revealed that the upconversion process is a multi-photon process.

Summary: In this study, a non-stoichiometric crystallisation in (K0.5Na0.5)NbO3 (KNN) synthesis was addressed using a non-aqueous solvothermal procedure. The results showed that oleic acid mediated solvothermal synthesis is an excellent technique to fabricate nanosized complex perovskites including KNN.

Summary: In this study, ultrasmall Eu3+-doped YVO4 nanocrystals with a PLQY of 62% were rapidly synthesized at room temperature by a facile ligand-assisted coprecipitation method. The as-prepared nanocrystals showed good dispersion with a particle size of 3.6 nm. These luminescent nanocrystals, with the advantages of room temperature preparation, high PLQY, and ultrasmall particle size, have high potential in lighting, display, anti-counterfeiting, and bioimaging.

Summary: The use of autoionization as a tool for quantitatively analyzing transitions between high-n strontium Rydberg states with low-to-intermediate values of L is demonstrated in this study. Rabi oscillations were observed when driving specific transitions using microwave fields. This technique offers advantages over selective field ionization and can be applied to other alkaline-earth and alkaline-earth-like metals.

Summary: This paper reports the successful synthesis of Cu2ZnSn1-xGexS4 (CZTGS) nanocrystals using a cost-effective solvothermal method, and investigates the effect of Ge on their structural, morphological, optical, and electrical properties. The results show that increasing Ge content leads to a transition in crystal structure from CZTS to CZGS, and an increase in band gap of resulting CZTGS nanocrystals.
