基于胶体半导体纳米结构的激光器可以从量子限制效应提供的显著光谱覆盖中受益。本文报道了利用圆柱微腔首次观察到溶液中的胶体CdSe/ZnS量子棒的激光(另见内封面)。球形纳米晶量子点也观察到了相同构型的激光。对于量子点，激光不是偏振的，但在量子棒中，激光发射是高度线偏振的，这是激光和光子应用的理想特征。
Lasers based on colloidal semiconductor nanostructures can benefit from the remarkable spectral coverage afforded through the quantum confinement effect. The first observation of lasing for colloidal CdSe/ZnS quantum rods in solution using a cylindrical microcavity is reported here (see also inside front cover). Lasing in the same configuration was also observed for spherical nanocrystal quantum dots. For the quantum dots lasing is not polarized, but in quantum rods the laser emission is highly linearly polarized, a desirable feature for laser and photonic applications.
