There is growing interest in white light emitting diodes for solid-state lighting and novel approaches for the synthesis of white light emitting materials is essential. The large pore gallium zinc phosphate NTHU-4 has been shown to emit light when photoexcited. NTHU-4 was successfully synthesized after only 4 h at 160 degrees C using a microwave oven, compared to 48 h at 160 degrees C by conventional heating. The effects of synthesis parameters on phase purity, crystal morphology and emission properties were explored. (C) 2008 Published by Elsevier Inc.
