| 摘 要： | IntroductionWith a suitable host matrix,the rare earth( RE) dopant ions can convert the lower energyphotons into higher- energy ones.Upconversionprocess is intensively investigated in order to obtainnew powdered phosphors and visible solid- statelasers.Recently,the upconverting phosphor tech-nology ( UPT) has been applied to producing thelateral flow test strips[1,2 ] .Upconverting phosphoris the same usefull biological label as quantumdot[3 ] .RE ions,especially erbium,due to its energylev… |
