Schematic illustration of MIR-to-Visible light upconversion device. ( ) Schematic illustration of MIR-to-Visible light upconversion device, ( ) Schematic representation of energy band diagram of the PbSe/ZnS QDPD and intersubband transition, the transfer of electrons from energy levels of ES to continuum using environment thermal energy causes to a dark current (blak circle, Idark) and photons excite electrons from energy levels of GS to energy levels of ES, causing a photocurrent (red circle, Iphoto).
