提高稀土上转换发光纳米材料荧光强度的方法

Method on enhancing fluorescence intensity of rare-earth upconversion fluorescent nanoparticles

针对稀土上转换纳米发光材料(UCNPs)发光强度低的缺陷,介绍了通过调整UCNPs的晶型和尺寸、金属离子掺杂、壳核结构、金属表面等离子体共振效应等因素提高UCNPs发光强度的方法。最后对提高UCNPs发光强度的研究做了展望。

Aiming at low fluorescence intensity of rare-earth upconversion fluorescent nanoparticles（UCNPs）,methods of improving the upconversion fluorescence intensity of UCNPs were summarized,such as adjusting the size and crystalline structure,metal ion doping,core-shell structure and surface plasmon resonance.Finally,the research to improve fluorescence intensity of UCNPs was prospected.
