Abstract

The glass systems with composition 20SrO-5CaO-40Li2O-(35-x) B2O3-x Eu2O3 (x = 0.3, 0.5 and 1 mol%) glasses were prepared by melt quenching technique to study absorption and luminescence properties and understand their lasing properties. The present work reports the studies on Physical, Optical and luminescence properties of the prepared glass systems. The photoluminescence (PL) intensity of the glass increases with increase in Eu2O3 content upto 1mol%. The increase in the density and decrease in molar volume reveals the close packing of glass network. For Eu3+ emission the most intense red emission has been observed at the wavelength of 614nm for the transitions 5D0 &

Keywords: Eu3+ ions, Photoluminescence, UV-Vis-NIR, Phonon side band, Lifetime.
