Abstract:
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 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.
