When quantum dots are irradiated by light, electrons within get energized, eventually releasing that energy as fluorescent light.

当量子点受到光照射时，内部的电子就会被激发，最终以荧光的形式释放出能量。

As they absorb light, electrons receive enough energy to jump across the junction between the layers, producing an electric current.

当电子吸收光时， 它们会获得足够的能量来跨越层之间的连接点，产生电流。
