| Abstract |
| This paper reports the preparation and structural studies of Pr3+-doped telluroborate
(TEB) glasses. The report aims to analyze combined Raman, Fourier transform infrared
(FTIR), optical and fluorescence spectra of Pr3+-doped TEB glasses and it was synthesized
using the melt quenching technique with glass system (50–x)B2O3.20TeO2.15Mg2CO3.
15K2CO3.xPr6O11 where x varies as 0, 0.4, 0.5, 1 and 1.5 mol%. The samples exhibited a
glassy appearance with a broad X-ray diffraction hump. Differently doped glasses
were studied structurally using FTIR and Raman spectroscopy. The Judd-Ofelt intensity
parameters, extracted from the optical absorption spectra of Pr3+, elegantly unveil the
intricate bonding environment surrounding the Pr3+ ions. To assess Pr3+-doped TEB
glass radiative properties, some important spectroscopic parameters were computed.
Here TEB glass having doping concentration 0.4 mol% exhibits higher stimulated
emission cross-section (e = 19.3710–20 cm2) and figure of merit (723.9610–26 cm2.s)
values which indicate its suitability for laser applications. The study includes
estimating colour coordinates to evaluate white light emission in Pr3+-doped glasses,
showcasing their potential for white light emitting diode applications.
