发现 YbP O 4 在红外（1 μm）光激发时显示出弱绿光（497 nm）发光。根据对激发强度依赖性和衰减时间的测量得出的结论是，这种发光是由于一对激发的 Yb 3+ 离子协同发射光子所致。
YbP O 4 was found to show weak green (497 nm) luminescence when excited by infrared (1 μm) light. It is concluded, on the basis of measurements of excitation intensity dependence and decay time, that this luminescence is due to the emission of a photon by a pair of excited Yb 3+ ions in cooperation.
