摘要
通过高温固相法制备了NaBaPO_(4)∶Er^(3+)荧光材料。采用化学还原法制备银纳米颗粒(银球与银立方),并修饰到NaBaPO_(4)∶Er^(3+)荧光材料中形成复合材料。利用银纳米颗粒表面等离激元特性实现了多激发光窗口激发下NaBaPO_(4)∶Er^(3+)多光子近红外量子剪裁发光增强。实现了在377 nm与485 nm光激发下,银球纳米颗粒表面等离激元增强NaBaPO_(4)∶Er^(3+)四光子与三光子近红外发光;在519 nm光激发下,银立方纳米颗粒表面等离激元增强NaBaPO_(4)∶Er^(3+)三光子近红外发光。
NaBaPO_(4)∶Er^(3+) was synthesized by solid-state reaction.Ag nanoparticles(NPs)(including Ag ball and Ag cube)were synthesized by chemical reduction method.The surface plasmon resonance of Ag NPs was utilized to enhance the multi-photon near infrared(NIR)quantum cutting emission intensity under multi-excitation.The surface plasmon resonance of Ag ball NPs was utilized to enhance the NIR emission intensity of four-photon and three-photon under the excitation of 377 nm and 485 nm,respectively.The surface plasmon resonance of Ag cube NPs was utilized to enhance three-photon NIR emission intensity under the excitation of 377 nm.
