Abstract
Official abstract text for this publication.
A photoexcitation material includes: a wurtzite type solid solution crystal containing gallium, zinc, nitrogen and oxygen, wherein a peak (A) of an existence ratio of nitrogen or oxygen which is a first adjacent atom of the gallium or zinc and a peak (B) of an existence ratio of gallium or zinc which is a second adjacent atom of the gallium or zinc satisfy a relational expression of A>B in a relationship between a distance and the existence ratio of the adjacent atom of the gallium or zinc, the relationship being obtained from an extended X-ray absorption fine structure analysis.
First claim
Opening claim text (preview).
What is claimed is: 1. A photoexcitation material comprising: a wurtzite type solid solution crystal containing gallium, zinc, nitrogen and oxygen, wherein a peak (A) of an existence ratio of nitrogen or oxygen which is a first adjacent atom of the gallium or zinc and a peak (B) of an existence ratio of gallium or zinc which is a second adjacent atom of the gallium or zinc satisfy a relational expression of A>B in a relationship between a distance and the existence ratio of the adjacent atom of the gallium or zinc, the relationship being obtained from an extended X-ray absorption fine structure analysis. 2. The photoexcitation material according to claim 1 , wherein the photoexcitation material is represented by Ga x N x Zn 1.00-x O 1.00-x , where x falls within a range of 0.00<x<1.00. 3. The photoexcitation material according to claim 2 , wherein x falls within a range of 0.25≤x≤0.75. 4. The photoexcitation material according to claim 3 , wherein the photoexcitation material has band gap energy of 2.5 eV or less.
