Manipulation of Irradiative Defects at MnSe and ZnSe Dopant-host Interface

摘要：

In the past few decades, trap emission was always believed hardly manipulated and harmful to the emission of luminescent quantum dots (QDs).Actually, not all trap emissions are useless.This work showed that interface between MnSe dopant and ZnSe host can be used for manipulate irradiative defects with a controllable manner.We focus on three basic challenges for manipulating interface defects, including (i) how to introduce irradiative defects at the dopant-host interface;(ii) how to control the intensity the interface trap emission, and (iii) how to tune QD emission color via the interface trap emission.Finally, we showed the application of dopant-host interface defects in ratiometric optical thermometry.
