SrAlO:Li,Mn phosphor-in-glass film: erosion behavior and luminescence property.

At present, phosphor-in-glass is regarded as a superior encapsulation material substituting for organic materials to resolve the poor thermal stability of WLEDs. However, the serious erosion reaction between commercial red phosphor and the glass matrix restricts the development and application of red phosphor-in-glass. In this work, a novel SrAlO:Li,Mn (SAO) red phosphor-in-glass film (PiGF) with precursor glass BO-(85 - )BiO-5AlO-10CaO was prepared using a low-temperature sintering technique.
