| titleOfInvention | Electrically-pumped laser based on manganese-doped quantum dots and preparation method thereof |
| abstract | The invention provides an electrically pumped laser based on manganese-doped quantum dots and a preparation method thereof. The electrically pumped laser comprises a light-transmitting substrate, a distributed feedback grating layer, a first conductive injection layer, and a CdS:Mn/ZnS core-shell quantum dot layer. , the second conductive injection layer and the reflective electrode layer; wherein, the CdS:Mn/ZnS core-shell quantum dot layer is used as an optical gain medium, because there is no absorption transition from the 6 A 1 state to the 4 T 1 state of the Mn 2+ ion, so the quantum At the emission wavelength of Mn 2+ ions, there is only emission but no absorption, and the energy of emission originates from the transfer of CdS nuclear band-edge states, so the zero-threshold optical gain can be achieved through the emission of Mn 2+ ions, which is based on CdS:Mn/ZnS The core-shell quantum dots are combined with the device structure to obtain an electrically pumped laser with zero threshold and high emission intensity. |
