| titleOfInvention | An infrared-visible optical up-conversion device |
| abstract | The invention discloses an infrared-visible optical up-conversion device. The up-conversion device includes an anode and a cathode, and a first organic light-emitting diode, an infrared photosensitive layer and a second organic light-emitting diode are sequentially arranged between the anode and the cathode. A diode, the infrared photosensitive layer is a material that has absorption in the infrared band, the first organic light emitting diode is sequentially provided with a first hole transport layer, a first light emitting layer and a first electron transport layer from bottom to top, the The second organic light emitting diode is sequentially provided with a second hole transport layer, a second light emitting layer and a second electron transport layer from bottom to top. The invention can simultaneously utilize photo-generated holes and photo-generated electrons to generate visible light emission, and the number of emitted visible light photons is twice the number of absorbed infrared light photons. High conversion efficiency of infrared-visible light can be achieved even in the wavelength band with weak absorption of infrared photosensitive materials. |
