Abstract

Ce³⁺ activated Y₃Al₅O₁₂ (YAG)-tellurite phosphor-in-glass (PiG) has been synthesized and the YAG:Ce³⁺ particles are well-distributed in glass matrix. The introduction of flux H₃BO₃ promotes crystal growth accompanying the generation of YBO₃ impurity phase, which leads to undesired blue light in precursor phosphor under ultraviolet (UV) irradiation. YAG-PiG composite releases efficient pure yellow light with the disappearance of blue light under UV excitation, indicating that the luminescence of the impurity phase is inhibited seriously. The composite combines the excellent formability of tellurite glass with the favorable luminescence capability of YAG:Ce³⁺, in which the impurity phase can be eliminated effectively during the fabrication of the composite. The excellent thermal stability and prominent fluorescence purification effect make YAG-PiG a potential candidate in developing high-quality yellow light source for optoelectronic clean-room lighting.
