UV-Vis Absorption and Luminescence Spectrum of LAS: Tb3+/Gd3 as a Laser Material (TECHNICAL NOTE)

Abstract

This article discusses details study on crystallization , optical properties of Li-Al-Si-La glass containing nanocrystalline LaF3.and their optical energy gaps. The Urbach energy of glass samples was evaluated. By using (2% mole) Tb the green–blue range emission occurred, while by accumulation 1% mole Gd beside Tb, the indigo emission intensity (418 to 441 nm) increased.
