Research Abstract

The phase-separated alkali metal-borosilicate glasses containing Cu^+clusters which exhibit warm color yellow luminescence under irradiation of ultraviolet(UV) LED light were prepared by use of a conventional melting method in order to achieve high power luminous material having high thermal and UV light stability. The obtained glass showed yellow luminescence of around 600 nm. The emission intensity increased largely by optimizing additive amounts of Cu ions and a reducing agent. The emission intensity increased much higher by incorporation of calcium oxide into the glass composition.
