| Article Name : | | | ABSORPTION AND EMISSION PROPERTIES OF PR(III) DOPED CALCIUM BORAX GLASSES | | Author Name : | | | SUJEET JAIN AND 1CHANCHAL PORWAL | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | ROR-528 | | Article : | |  | Author Profile | | Abstract : | | | Optical absorption and photoluminescence spectra of Pr(III) doped calcium borax glasses are presented. The observed spectra have been analyzed to calculate oscillator strengths (ƒ), the Judd-Ofelt intensity parameters (Ωλ). The radiative parameters namely, transition probabilities (A, Aτ), branching ratios (βR %), lifetimes (τR μsec) and stimulated emission cross-sections (σP λcm2) are also evaluated for the different glass compositions and shown to change with chemical compositions. | | Keywords : | | - Judd-Ofelt
