Abstract
Official abstract text for this publication.
Provided are a titanium dioxide-coated upconverting nanoparticle (UCNP) and a photocatalyst complex containing a gold nanorod (GNR) combined with the titanium dioxide-coated UCNP.
First claim
Opening claim text (preview).
The invention claimed is: 1. A photocatalyst composite comprising: upconverting nanoparticles coated with a photocatalytic metal oxide; and gold nanorods. 2. The photocatalyst composite according to claim 1 , wherein the number of upconverting nanoparticles is 2 to 8 times the number of gold nanorods. 3. The photocatalyst composite according to claim 1 , wherein the upconverting nanoparticles comprise a rare-earth element. 4. The photocatalyst composite according to claim 1 , wherein the photocatalytic metal oxide comprises at least one selected from the group consisting of titanium dioxide, tungsten oxide, zinc oxide, niobium oxide, and a combination thereof. 5. The photocatalyst composite according to claim 1 , wherein the upconverting nanoparticles have an average diameter of 5 nm to 40 nm. 6. The photocatalyst composite according to claim 1 , wherein the photocatalytic metal oxide is coated onto the upconverting nanoparticles to an average thickness of 2 nm to 20 nm. 7. The photocatalyst composite according to claim 1 , wherein the gold nanorods have a rod shape, the shortest diameter of which ranges from 5 nm to 30 nm and the length of a major axis of which ranges from 30 nm to 150 nm. 8. The photocatalyst composite according to claim 1 , wherein the upconverting nanoparticles coated with the photocatalytic metal oxide are physically or chemically bonded to the gold nanorods. 9. The photocatalyst composite according to claim 1 , wherein the upconverting nanoparticles coated with the photocatalytic metal oxide are physically or chemically bonded to the gold nanorods through an intermediate compound. 10. The photocatalyst composite according to claim 1 , wherein the upconverting nanoparticles coated with the photocatalytic metal oxide are bonded to the gold nanorods directly or through intermediate compounds. 11. The photocatalyst composite according to claim 1 , wherein the photocatalyst composite is obtained by introducing a combination of streptavidin and biotin or a combination of an amine compound and a carboxyl acid-containing compound, as the intermediate compounds, to surfaces of the photocatalytic metal oxide and the gold nanorods, respectively, and bonding the upconverting nanoparticles to the gold nanorods.
