量子点是半径小于或接近于激子玻尔半径的一类半导体纳米粒子,具有宽的激发光谱、窄的发射光谱、可精确调谐的发射波长、可忽略的光漂白等优越的荧光特性,是一类理想的荧光探针.本文就II-VI型量子点在分析应用中最新进展做一简要的评述.
Quantum dots are a class of semiconductor nanoparticles with radius less than or close to the exciton Bohr radius. They have wide excitation spectrum, narrow emission spectrum, precisely tuned emission wavelength and negligible photobleaching. A kind of ideal fluorescent probe.In this paper, a brief review is given on the latest progress of the application of II-VI quantum dots in the analysis.
