Abstract:

Yellow-emitting BCNO phosphors, applied for white light-emitting-diodes (LEDs), were synthesized by a facile microwave heating route at lower temperature within short duration. The prepared BCNO phosphors exhibited amorphous form and tunable yellow emission in the range of 510-550 nm under the excitation of 450-nm blue light. The effects of carbon content on the photoluminescence properties for these BCNO phosphors and their application performances in white LEDs were investigated in detail. The demonstrated microwave synthesis route is promising in preparing low-cost phosphors, and the prepared BCNO phosphor may find potential application in blue-based white LEDs.
