Abstract The Nb3⁺ doped Zinc Borophosphate glass (30B2O3 +35P2O5+5TiO2+10ZnO+9LiCO3+10 BaCO3+1NbO2) has been synthesized successfully using melt-quenching method. The powder X-ray diffraction (XRD) analysis was used to find the glass nature of Nb3⁺ doped Zinc Borophosphate glass. The functional group of Nb3⁺ doped Zinc Borophosphate glass was recognized using Fourier-transform infrared spectroscopy (FTIR) analyses. Linear optical properties of the Nb3⁺ doped Zinc Borophosphate glass were studied using UV–vis–NIR spectrum in the room temperature. Mechanical behaviour of Nb3⁺ doped Zinc Borophosphate glass was examined through Vicker’s hardness method. The mechanical properties of Nb3⁺ doped Zinc Borophosphate glass was examined with various loads. The emission transitions of Nb3⁺ doped Zinc Borophosphate glass was studied using Photoluminescence analysis. The CIE diagram of the Photoluminescence was examined. Gamma ray shielding parameters such half value layer, mean free path and mass attenuation coefficient of Nb3⁺ doped Zinc Borophosphate glass were studied using Phy-X software.

Abstract The slow evaporation technique was used to produce nonlinear optical ammonium pentaborate dihydrate (APBDH) single crystals. The crystal lattice parameters and structure of APBDH crystal was determined by single crystal X-ray diffraction (S-XRD) technique with the triclinic space group. The optical band gap of the grown crystal was determined using UV–Vis spectrophotometer. There is no absorption peak was observed in the entire visible region of the spectrum. The functional groups of the APBDH crystal were identified through Fourier transforms infrared (FTIR) and Fourier transform Raman (FR-Raman) analyses. The thermal decomposition and thermal stability of the grown crystal was measured using TG-DTA analyses. The laser damage threshold (LDT) analysis was used to know the ability to withstand the influence of laser on the grown crystal. Photoconductivity of the grown crystal was studied and its photocurrent and dark current behavior was examined. The surface morphology of the APBDH crystal was evaluated using HR-SEM analysis. The APBDH crystal was exhibited second harmonic generation behavior and its efficiency was calculated with different particle sizes.

Pure and Zn doped manganese (II, III) oxide (Mn3O4) nanoparticles were prepared by simple chemical precipitation method at room temperature with different atomic percentages (6, 12, 18) of Zn. The obtained products were subjected to various characterizations namely powder X-ray diffraction (XRD), microstructure and morphology were investigated by scanning and transmission electron microscopy (SEM and TEM), element analysis was done by energy-dispersive X-ray spectroscopy (EDX). Specific surface area of all the samples were measured by Brunauer–Emmett–Teller (BET) analysis. The optical absorption (UV-vis) property of the samples, confirmed electronic transitions and increase in the band gap of the products. The as-synthesized samples were used for degrading methylene blue (MB) dye of which 12at% Zn in Mn3O4 showed best oxidation efficiency compared to other samples.
