Document Type and Number:
WIPO Patent Application WO/2015/119125
Kind Code:
A1
Abstract:
The present invention pertains to a production method for phosphor microparticles, a phosphor thin film, a wavelength conversion film, a wavelength conversion device, and a solar cell. A production method for phosphor microparticles in which phosphor microparticles having a perovskite structure indicated by (Ca, Sr) TiO3: Pr3+ and having a particle diameter of no more than 100 nm at most are produced, said production method having a step in which a raw material selected from Ca, Sr, and Ti ions, an oxide or a hydride is caused to have a hydrothermal reaction with a raw material comprising Pr ions, in water in a subcritical to a supercritical state, the molar ratio of (Ca+Sr)/Ti in the raw material composition being 1.0-2.5.
