LIGHT EXCITATION MATERIAL, PHOTOCHEMICAL ELECTRODE, AND MANUFACTURING METHOD OF LIGHT EXCITATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a light excitation material or the like of narrow prohibition band width capable of using light energy at high efficiency.SOLUTION: There is provided a light excitation material which is a solid solution body of MN, where M is at least one of Ga, Al and In, and ZnO and has content of the ZnO of 30 mol% or more and 70 mol% or less and band-gap energy of 2.20 eV or less.SELECTED DRAWING: Figure 1
