Borate Glasses for Luminescence Applications - Potential Materials for White LEDs and Laser Sources

Abstract

The development of borate based glasses for luminescence applications are reviewed. The present work covers various aspects including the search and synthesis of new materials, the formation of glasses, the structural and optical properties of absorption, excitation and luminescence on the prepared glasses, Information on the Judd-Ofelt intensity parameters as calculated from absorption spectra and the studies on the emission properties. CIE colour coordinates are helpful to analyze the potentiality of the glasses for white light emission. We aim to provide a comprehensive review of borate glass materials for LED and screen display applications etc.
