Title:
WAVELENGTH CONVERSION DEVICE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/174226
Kind Code:
A1
Abstract:
A wavelength conversion device, comprising a substrate (100) and a diffuse reflection layer (200) provided on the substrate. The diffuse reflection layer comprises white diffuse reflection particles (210) and a binder (220). The white diffuse reflection particles comprise main diffuse reflection particles (211) and auxiliary particles (212), the range of the particle size of the main diffuse reflection particles being 0.1-10 µm and the range of the particle size of the auxiliary particles being 10-100 nm. By jointly forming a diffuse reflection layer by submicro diffuse reflection particles and nano diffuse reflection particles, higher reflectivity is implemented. In addition, the diffuse reflection layer and a substrate can be well bounden, thereby implementing higher efficiency and brightness of a wavelength conversion device.
