摘要：

The optical properties of near-infrared-emitting mercury telluride (HgTe) nanocrystals are investigated using fluorescence confocal microscopy. The HgTe quantum dots were coated with a "layer-by-layer" process on latex spheres with diameters down to 150 nm and number of layers varying from 1 to 3. The individual spheres act as bright subwavelength light sources. Measurements of the fluorescence decay show that the lifetime varies with the number of nanocrystal layers.
