Quantum dots are a kind of semiconductor nanopaticles with the radius equal to or less than the exciton Bohr radius. They have tremendous potential in the field of biology and medicine because of their unique and tunable optical properties (broad excitation spectrum, narrow emission spectrum, precise tunability of their emission peak and negligible bleaching, etc) as new fluoresent probes.

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晶，作为一种新型的荧光标记物，其独特和可调谐的光学特性（宽的激发光谱、窄的发射光谱、可精确调谐的发射波长以及可忽略的光漂白等）使其在生物和医学方面显示出巨大的应用潜力。

The small band gap and the large Bohr radius of lead chalcogenides enable unique optical, electrical, and chemical properties, presenting this family of materials as a good candidate for potential applications in solar cells, thermoelectric devices, telecommunication, field effect transistors and biological imaging.

IV-VI族铅的硫属化合物半导体纳米材料，由于他们较小的能带间隙和较大的激子波尔半径，这类材料在太阳能电池，热电器件，电子通信，场效应晶体管，生物成像技术上有很广泛的潜在应用价值。

We also studied the resonant Raman-scattering in the ZnCdSe/ZnSe QWs with different well width, and found the Raman signal can be only observed in the QWs with width comparable to the Bohr radius of the excitons in the ZnCdSe QWs, which implies the strong correlation between the electrophonon interaction and the quantum confinement effect.

通过采用不同宽度的量子阱，我们研究了ZnCdSe/ZnSe单量子阱的共振喇曼散射特性，发现共振喇曼散射信号只在阱宽与激子玻尔半径相当的单量子阱中（5nm和2.5nm）才能观察到。
