Abstract

The present application relates to a method for dispersing quantum dots (QDs) or quantum wires in zeolite, to zeolite containing quantum dots or quantum wires dispersed by the method, and to a method for stabilizing quantum dots or quantum wires in zeolite.

First claim

What is claimed is:

1. A dispersing method of quantum dots or quantum wires in zeolite, the method comprising:
treating zeolite containing quantum dots or quantum wires using a basic gas,
wherein the basic gas includes NH 3 , PH 3 , AsH 3 , amine gases, or combinations thereof.

2. The dispersing method of claim 1 , wherein the quantum dots or the quantum wires are uniformly dispersed in pores of the zeolite.

3. The dispersing method of claim 1 , wherein the quantum dots or the quantum wires include a metal, an oxide, or a compound semiconductor.

4. The dispersion method of claim 1 , wherein the quantum dots or the quantum wires are dispersed in an isolated state from each other in the pores of the zeolite.

5. The dispersing method of claim 1 , wherein the quantum dots or the quantum wires are stably dispersed in the zeolite under an atmosphere.

6. The dispersing method of claim 1 ,
wherein the zeolite includes zeolite Y, zeolite X, zeolite A, zeolite L, mordenite, gallosilicate, borosilicate, silicoaluminophosphate, or aluminophosphate.

7. Quantum dot- or quantum wire-containing zeolite which comprises dispersed quantum dots or dispersed quantum wires, wherein the quantum dots or the quantum wires are dispersed in the zeolite by the dispersing method of any one of claims 1 - 3 and 4 - 6 .

8. The quantum dot- or quantum wire-containing zeolite of claim 7 , wherein the quantum dots or the quantum wires are uniformly dispersed in pores of the zeolite.

9. The quantum dot- or quantum wire-containing zeolite of claim 7 , wherein the quantum dots or the quantum wires include a metal, an oxide, or a compound semiconductor.

10. The quantum dot- or quantum wire-containing zeolite of claim 9 , wherein the compound semiconductor includes a member selected from the group consisting of CdS, CdO, CdSe, CdTe, ZnS, ZnO, ZnSe, ZnTe, MnS, MnO, MnSe, MnTe, MgO, MgS, MgSe, MgTe, CaO, CaS, CaSe, CaTe, SrO, SrS, SrSe, SrTe, BaO, BaS, BaSe, BaTE, HgO, HgS, HgSe, HgTe, Al 2 O 3 , Al 2 S 3 , Al 2 Se 3 , Al 2 Te 3 , Ga 2 O 3 , Ga 2 S 3 , Ga 2 Se 3 , Ga 2 Te 3 , In 2 O 3 , In 2 S 3 , In 2 Se 3 , In 2 Te 3 , SiO 2 , GeO 2 , SnO 2 , SnS, SnSe, SnTe, PbO, PbO 2 , PbS, PbSe, PbTe, AlN, AlP, AlAs, AlSb, GaN, GaP, GaAs, GaSb, InN, InP, InAs, InSb, BP, Si, Ge, and combinations thereof.

11. The quantum dot- or quantum wire-containing zeolite of claim 7 , wherein the quantum dots or the quantum wires are dispersed in an isolated state from each other in the pores of the zeolite.

12. The quantum dot- or quantum wire-containing zeolite of claim 7 , wherein the quantum dots or the quantum wires are stably dispersed in the zeolite under an atmosphere.

13. The quantum dot- or quantum wire-containing zeolite of claim 7 , wherein the zeolite includes zeolite Y, zeolite X, zeolite A, zeolite L, mordenite, gallosilicate, borosilicate, silicoaluminophosphate, or aluminophosphate.

14. A stabilizing method of quantum dots or quantum wires in zeolite, the method comprising:
treating zeolite containing quantum dots or quantum wires with a basic gas to disperse the quantum dots or the quantum wires in the zeolite, wherein the basic gas includes NH 3 , PH 3 , AsH 3 , amine gases, or combinations thereof.

15. The stabilizing method of claim 14 , wherein the quantum dots or the quantum wires are uniformly dispersed in pores of the zeolite.

16. The stabilizing method of claim 14 , wherein the quantum dots or the quantum wires include a metal, an oxide, or a compound semiconductor.

17. The stabilizing method of claim 14 , wherein the quantum dots or the quantum wires are dispersed in an isolated state from each other in the pores of the zeolite.
