γ-LiAlO_2：Tb~（3＋）绿色荧光粉制备及其发光性能
Preparation and Luminescent Characteristics of the γ-LiAlO_2：Tb~（3＋） Green Phosphor
摘要
Abstract
The γ-LiAlO2：Tb3＋phosphor was synthesized by citric acid sol-gel method,and its excitation and emission spectra was investigated.γ-LiAlO2：Tb3＋has several emission peaks,and these are located at 489,542,584 and 620 nm,which correspond to the 5D4→7FJ,（J=6,5,4,3） transitions of Tb3＋,respectively.The main peak is at 542 nm.The strongest excitation peak at 238 nm of the powder（monitored at an emission wavelength of 542 nm） belongs to the broadband excitation.The effect of amount of Tb3＋ doping content,the charge compensation agent（Li＋） on the emission intensity of the γ-LiAlO2：Tb3＋phosphor were also studied.The results showed that the emission intensity can be controlled by the above factors,and the intensity can be enhanced by selecting the prime optimum conditions.关键词
