<P>PROBLEM TO BE SOLVED: To provide a wavelength conversion element in which the wavelength conversion region is improved and reflection loss of incident light is also improved, and to provide a photoelectric conversion device comprising the wavelength conversion element. <P>SOLUTION: The wavelength conversion element has at least one wavelength conversion layer comprising a matrix layer composed of a curable resin material or an inorganic material having a band gap of 3 eV or larger, and particles having grain size of 3-20 nm composed of a wavelength conversion composition provided in the matrix layer and performing wavelength conversion to the light having energy lower than that of the light absorbed, for a specific wavelength region of the light absorbed. The particles are arranged so that the distance between the adjacent particles is shorter than the grain size. Consequently, reflection of light in wavelength regions other than the specific wavelength region is prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
