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

This article discusses detailed 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 wasevaluated. 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
