Abstract
Official abstract text for this publication.
The present invention addresses the issue of providing an optical selective film that contributes to efficiently converting light into heat. This optical selective film is characterized in that: the optical selective film includes at least an Ag-containing layer, and an Ag diffusion prevention layer that is disposed adjacent to the Ag-containing layer; and the Ag diffusion prevention layer contains FeSi x (X=1 to 2).
First claim
Opening claim text (preview).
The invention claimed is: 1. An optical selective film including at least an Ag-containing layer and an Ag anti-diffusion layer situated adjacent to the Ag-containing layer, the Ag anti-diffusion layer including FeSi X (X=1 to 2), wherein the Ag-containing layer is an infrared-reflecting film, and at least the Ag-containing layer and the Ag anti-diffusion layer are laminated in that order. 2. The optical selective film according to claim 1 , wherein the FeSi X is FeSi 2 (X=2). 3. The optical selective film according to claim 2 , wherein the FeSi 2 is β-FeSi 2 . 4. The optical selective film according to claim 2 , wherein the FeSi 2 is α-FeSi 2 . 5. An optical selective film including at least an Ag-containing layer and an Ag anti-diffusion layer situated adjacent to the Ag-containing layer, the Ag anti-diffusion layer including FeSi X (X=1 to 2), wherein the Ag-containing layer is an infrared-reflecting film, and at least the Ag anti-diffusion layer, the Ag-containing layer and the Ag anti-diffusion layer are laminated in that order. 6. The optical selective film according to claim 5 , wherein the FeSi X is FeSi 2 (X=2). 7. The optical selective film according to claim 6 , wherein the FeSi 2 is β-FeSi 2 . 8. The optical selective film according to claim 6 , wherein the FeSi 2 is α-FeSi 2 .
