| titleOfInvention | Vertical cavity surface emitting laser containing silver sulfide/silver sulfide zinc core-shell quantum dots and preparation method thereof |
| abstract | The invention discloses a vertical cavity surface emitting laser containing silver sulfide/silver sulfide zinc core-shell quantum dots and a preparation method thereof. The vertical cavity surface emitting laser comprises a quartz substrate arranged upward in sequence, a lower high-reflection mirror, a Silica layer and upper mirror of silver sulfide/silver-zinc sulfide core-shell quantum dots. In the invention, the silver sulfide quantum dots with the lowest quantum state 2-fold degeneracy are used to replace the lead salt quantum dots with the lowest quantum state 8-fold degeneracy to realize the near-infrared light gain with low threshold value. The silver-zinc alloy shell with gradually increasing zinc content from the inside to the outside can build a smooth interfacial barrier and passivate the surface of the silver sulfide quantum dots, which can further reduce the optical gain threshold. The silicon dioxide film containing silver sulfide/silver zinc sulfide core-shell quantum dots is "sandwiched" between two high-reflection mirrors, and finally a low threshold, high quality factor and environmentally friendly vertical cavity surface emission near-infrared quantum dots can be obtained. point laser. |
