Investigation on structural, optical properties of Sm3+ doped antimony boro-phosphate glass for warm white light emitting diode and radiation shielding applications

The melt-quench technique was used to produce the rare earth element Sm3+ doped Antimony Boro-Phosphate glass. The amorphous nature of the Sm3+ doped Antimony Boro-Phosphate glass was verified by the powder X-ray diffraction pattern. With the use of FTIR, the functional groups of the Sm3+ doped Antimony Boro-Phosphate glass were determined calculations were made for the optical-bandgap energy and absorption using the Uv-Vis spectroscopic analysis. Among the optical metrics that were calculated and investigated were the refractive index, optical conductivity, and extinction coefficient. Using photoluminescence analysis, the excitation and emission spectra of Sm3+ doped Antimony Boro-Phosphate glass were investigated. The warm white color of the glass that was produced was verified by the chromaticity coordinates. SEM investigation was performed on the produced glass, and the surface morphology of the Sm3+ doped Antimony Boro-Phosphate glass was investigated. Phy-X software was employed to examine the gamma shielding behavior of Sm3+ doped antimony-phosphate glass, including the mass attenuation coefficient, mean free path, half-value layer, and effective atomic number.
