Abstract
The glass composition P2O5 60%, SrO 40% (mol%) was prepared then doped with Sm3+ with different mol% (3.2, 6.4, 9.6 and 15%). UV–VIS–NIR spectrometer was used to carry out the absorption spectra of the studied glass samples. The most nominal transitions were assigned among a large number of transitions. Then the radiative properties of the Sm3+ ions were calculated using J–O analysis. The results show a large value of Ω2 than the values Ω4 and Ω6. Another parameter such as the oscillator strength, radiative life time, the transition probabilities, the spectroscopic quality and factors branching ratio of several excited states of the Sm3+ ions was calculated. The laser transition level from 6F9/2→6H5/2, the gain cross-section has been predicted. The emission profile of Sm3+ ions in the present glass shows that the peak of the gain coefficient is shifted toward shorter wavelength as the increase of the inversion. The Optical properties introduce this doped Sm3+ glass as a promising candidate for optical applications.
