We present colloidal silica microspheres encapsulating a homogeneous quantum dot layer at radial equidistance from the centre by utilizing electrostatic interaction between surface-engineered silica microspheres and QDs. The microspheres show dramatically enhanced optical absorption and emission with an appropriate silica shell thickness.
我们通过利用表面修饰的二氧化硅微球和量子点之间的静电相互作用，在径向等距处将胶体二氧化硅微球包裹在均匀的量子点层中。当二氧化硅壳层厚度适当时，微球表现出显著增强的光学吸收和发射。
