The average crystallite size was found to be about 30nm. It was revealed from photoluminescence spectra that there was an excitation band around 368 nm and a narrow excitation peak at 468 nm. The emission spectrum showed four peaks at 589, 608, 629 and 650 nm.展开更多
文摘Europium doped CeO_2 was synthesized via combustion synthesis method. The powders were found to be in a single phase. The average crystallite size was found to be about 30nm. It was revealed from photoluminescence spectra that there was an excitation band around 368 nm and a narrow excitation peak at 468 nm. The emission spectrum showed four peaks at 589, 608, 629 and 650 nm.
