Fabrication of phosphor ceramic plate using green-emitting Lu3Al5O12:Ce3+ phosphor for high power LEDs

Lu3Al5O12:Ce3+ phosphor ceramic plates can be combined with blue chips to produce white light emitting diodes (WLEDs). Lu3Al5O12:Ce3+ was synthesized using a solid state reaction and was sintered under a reduction atmosphere. The phosphor ceramic plates exhibited good thermal effects with a Lu3Al5O12:Ce3+ phosphor ceramic plates of varying thickness. Lu3Al5O12:Ce3+ phosphor ceramic plates also exhibited quenching properties at extraordinarily high temperatures. We suggest that Lu3Al5O12:Ce3+ phosphor ceramic plates can be a candidate for next-generation high-power LEDs. •Thermally stable ceramic phosphor plate was fabricated using Lu3Al5O12: Ce3+ phosphor.•An increase in the forward-bias current from 0 to 350mA shifts the color point of the white LEDs upward.•Our approach can be a candidate as an alternative for application in high power LEDs.
