PEROVSKITE/POLYMER COMPOSITE LUMINESCENT MATERIAL PREPARATION METHOD AND APPLICATION

摘要

The present invention provides a composite light emitting material. The composite light emitting material includes a matrix and perovskite-type nanoparticles, the perovskite-type nanoparticles are dispersed in the matrix, and the mass ratio of the perovskite-type nanoparticles to the matrix is 1 :( 1-50).
