Title:
LIGHT CONVERSION DEVICE AND PREPARATION METHOD THEREFOR, AND INFRARED IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/019661
Kind Code:
A1
Abstract:
A light conversion device and a preparation method therefor, and an infrared imaging device. In the light conversion device, a photosensitive component and a light emitting component are disposed in parallel on a substrate and connected by a connecting component. When the device is in an operating state, the photosensitive component converts an input non-visible light signal into photogenerated electrons, and the photogenerated electrons are injected into the light emitting component by means of the connecting component. The photogenerated electrons injected into the light emitting component drive the light emitting component to emit visible light, such that the device has highly efficient light-sensing and light-emitting capabilities. Further, due to the compact structure, small size, and light weight of the device, the device meets requirements for the preparation of portable infrared imaging devices. The preparation method for the light conversion device includes a simple preparation process and is suitable for large-scale manufacturing.
