Abstract
Phosphor in glass (PiG) employing Ce:Y3Al5O12 (YAG)-doped boro-bismuthate glass via low-temperature co-sintering technology was successfully prepared, using Bi2O3-B2O3-ZnO glass as the base material. The photoluminescence (PL) of PiG co-sintered at times ranging from 20 min to 60 min at 700°C was investigated. As a result, the relative PL intensity of PiG under a reducing atmosphere of CO showed significant enhancement of about 7–14 times that under air atmosphere sintering for 20–50 min. The PL intensity decreased gradually with the co-sintering time, which may be due to the corrosion of the YAG lattice structure.
