Ultraviolet ray detection apparatus using nanocrystal quantum dot
An ultraviolet rays detection apparatus according to the present invention includes a color converting unit including nanocrystal quantum dots and having a color that is changed by irradiation of ultraviolet rays, and a non-color-converting unit disposed closer to the color converting unit and having a color that is not changed by the irradiation of the ultraviolet rays, thereby easily detecting the ultraviolet rays.
1. An ultraviolet rays detection apparatus comprising:
a color converting unit including nanocrystal quantum dots and having a color that is changed by an irradiation of an ultraviolet rays; and
a non-color-converting unit disposed adjacent to the color converting unit and having a color that is not changed by the irradiation of the ultraviolet rays.
2. The ultraviolet rays detection apparatus of claim 1 , wherein
the color converting unit and the non-color-converting unit include particles and are mixed and deposited to thereby form a layer.
3. The ultraviolet rays detection apparatus of claim 1 , further comprising
a substrate disposed under or on the color converting unit.
4. The ultraviolet ray detection apparatus of claim 1 , wherein
the color converting unit is made of a color converting layer in which the particles are continuously disposed, and the non-color-converting unit is made of a non-color-converting layer in which the particles are continuously disposed.
5. The ultraviolet ray detection apparatus of claim 4 , wherein
the non-color-converting layer is disposed on the color converting layer and is translucent.
6. The ultraviolet ray detection apparatus of claim 4 , wherein
the non-color-converting layer is disposed under the color converting layer.
7. The ultraviolet ray detection apparatus of claim 4 , wherein
the non-color-converting layer is made of a substrate having a color.
8. The ultraviolet ray detection apparatus of claim 4 , wherein
the color converting layer is formed by spincoating a solution including the nanocrystal quantum dots.
9. The ultraviolet ray detection apparatus of claim 1 , wherein
a comparison color table having a color that is changed according to irradiation intensity of the ultraviolet rays is attached.
10. The ultraviolet ray detection apparatus of claim 1 , wherein
the color of the color converting unit expressed by the irradiation of the ultraviolet rays and the color of the non-color-converting unit have a complementary color relationship.
11. The ultraviolet ray detection apparatus of claim 1 , wherein
the nanocrystal quantum dots are made of one material selected from a group including group 2-3 family materials, group 3-5 family materials, and group 4 family materials, or combinations thereof.
12. The ultraviolet ray detection apparatus of claim 1 , wherein
the nanocrystal quantum dots further include an inorganic shell enclosing a surface.
