Abstract

Ce3+ activated Lu3Al5O12 (LuAG) phosphor-in-glass (PiG) based on tellurite glass with low melting temperature has been synthesized and the LuAG particles are proved to be well-distributed in tellurite glass with the particle size of ~5 μm. The introduction of H3BO3 as a flux is helpful to promote polycrystalline growth and reduce reaction temperature of LuAG:Ce3+ green phosphor, but accompanied by the generation of LuBO3 impurity phase. Differential fluorescence emission behaviors between LuAG:Ce3+ and LuAG-PiG illustrate that the luminous ability of the LuBO3:Ce3+ is strongly restrained while intense pure green light is released in composite. LuAG-PiG combines the admirable formability of tellurite glass with the favorable luminescent capability of LuAG:Ce3+, in which LuBO3 can be effectively eliminated to achieve LuAG:Ce3+ depuration. Prominent depuration capacity and intense fluorescence emission demonstrate that LuAG-PiG is a potential candidate in developing high-power light emitting diodes lighting.
