The inversed polarization will disappear under a strong electric field and the singleexcitedstate of a polaron will dissociate into a polaron and a bipolaron.
在强电场下，反向极化消失，极化子单激发态解离为一个单极化子和一个双极化子态。

The luminescence intensity is high and stable. Single quantum dots have longer excitedstate lifetimes, and they appear 10-20 times brighter than organic fluorescent dyes.
