Purification of Ce3+ yellow-fluorescence in UV-pumped Y3Al5O12-tellurite phosphor-in-glass
Source abstract
Abstract
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.
