摘要：

Tb-doped YPO(4)center dot 2H(2)O was synthesized via a simple wet-chemical route. Both the crystallinity of samples and the concentration of OH- adsorbed at the surface were experimentally controlled by adjusting the reaction time. An abnormal phenomenon that photoluminescence efficiency decreases with the increase of crystallinity demonstrates enormously adverse effect of OH- on photoluminescence, especially, as the OH- content reaches a critical value, the luminescent efficiency decreases more drastically. This strong dependence of photoluminescence on the OH- content indicates that to control the OH- content in a limited range or to reduce the OH- effect as much as possible is an efficient way to improve photoluminescence efficiency.
