Absorption and emission properties of Pr3+ activated Be2La2O5 crystal

摘要

Abstract: THe spectroscopic properties of trivalent praseodymium doped Be$-2$/La$-2$/O$-5$/ crystals have been investigated at various temperatures. The absorption, emission, excitation and fluorescence lifetime measurements for a sample containing 1 atomic percent of activator have been performed and discussed. The Judd-Ofelt theory has been applied to obtain approximately ega$-i$/ intensity parameters. !6
