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. Thepresent 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 up to 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 transitions5D0 →7F2. The phonon energy was measured from phonon side band spectra which showed 1280cm−1, typical value for the borate glasses. Luminescence intensity ratio and lifetime analysis has been measured and discussed in the present work. The present glasses are very near to reddish orangeregion and thus can be key entrant for optical display device applications.
