Thermally tunable amplified spontaneous emission from Cu2ZnSnS4 quantum dot doped photonic cavity by a soft solvothermal route

Abstract

In this article, non-toxic Cu₂ZnSnS₄ quantum dots (CZTSQDs) were synthesized by the solvothermal method and then embedded into a photonic cavity to tune the amplified spontaneous emission of the device. The amplified spontaneous mechanism was investigated based on the liquid crystal cavity structure and fluorescence behaviours. The results clearly indicate that employing CZTSQDs in creating novel composites allows for the fabrication of active medium materials with thermally tunable emission properties.
