A light-emitting device, comprising a substrate (101), a blue light source generation panel (102) and a photoluminescence layer (103). The substrate (101) comprises a first surface and a second surface. The blue light source generation panel (102) is arranged on the first surface of the substrate (101) and is used for generating blue light. The photoluminescence layer (103) is arranged on the second surface of the substrate (101) and is used for generating white light under the irradiation of the blue light. The light-emitting device can be prepared by means of a relatively simple process, and has relatively high light-emitting stability and relatively long service life. |
