A perovskite phosphor film emitting red light from among the three primary colors (i.e., red, green and blue) underlying the construction of displays which is fabricated by adsorbing a nanosheet as a seed layer on a solid substrate and forming an oriented film of an oxide phosphor thereon, characterized in that the perovskite phosphor film comprises a film of an oxide phosphor ( 3 ) having a high transparency that is formed on a seed layer comprising a nanosheet ( 2 ) that is adsorbed on a solid substrate ( 1 ) such as a glass substrate or the like, and the oxide phosphor ( 3 ) is (Sr x Ca 1-x ) 1-y ,Pr y TiO 3 : 0≦x≦0.8, 0.001≦y≦0.01. |
