Abstract
Disclosed are a method for preparing a fluorescent nanomaterial-polymer composite and a wavelength converting element, and a light emitting device. The method for preparing the fluorescent nanomaterial-polymer composite includes: at least one precursor provided, the precursor includes a fluorescent nanomaterial and a polymer; and in a first temperature at or higher than a melting point of the polymer, the precursor is mixed, and then cooled.
