Abstract
The present disclosure relates to a wavelength conversion apparatus and a manufacturing method therefor. The wavelength conversion apparatus comprises a light-emitting layer, a reflective film, a sintering silver layer, and a substrate stacked successively. The light-emitting layer converts an excitation light into exit light having a different wavelength from the excitation light. The reflective film is plated on the light-emitting layer and used for reflecting the exit light emitted by the light-emitting layer. The sintering silver layer is connected to the light-emitting layer and the substrate; the sintering silver layer comprises flake silver particles connected with each other via surface contact; and the sintering silver layer is formed by sintering spherical silver nanoparticles and flake silver particles. The wavelength conversion apparatus is characterized by excellent thermal conductivity and high luminous efficiency.
