Abstract
Provided are a photon up-conversion film, which is capable, of high-efficiency up-conversion even in air and even when low-intensity light is used, and a simple method of producing the film. The photon up-conversion film according to one embodiment of the present invention includes: a matrix including a resin; and a pore portion, wherein the photon up-conversion film includes at least a sensitizing component capable of absorbing light in a first wavelength region λ1, and a light-emitting component capable of radiating light in a second wavelength region λ2 including wavelengths shorter than those of the first wavelength region λ1, and wherein the sensitizing component and the light-emitting component are present at an interface between the matrix and the pore portion.
