【摘要】 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.更多还原

【Abstract】 Quantum dots are a kind of semicoductor nanopaticles which radius is near or smaller than the exciton Bohr radius. They have broad excitation spectrum, narrow emission spectrum, precise tunability of their emission peak and negligible bleaching etal as fluorescence probes. We review recent advances in the development of II-VI type quantum dots for analysis.更多还原
