Abstract

There is provided a quantum dot wavelength converter including a quantum dot, which is optically stable without any change in an emission wavelength and improved in emission capability. The quantum dot wavelength converter includes: a wavelength converting part including a quantum dot wavelength-converting excitation light and generating a wavelength-converted light and a dispersive medium dispersing the quantum dot; and a sealer sealing the wavelength converting part.

Claims (9)

1 - 8 . (canceled)

9 . A method of manufacturing a quantum dot wavelength converter, the method comprising:

dispersing a quantum dot wavelength-converting excitation light and generating a wavelength-converted light in a dispersive medium to prepare a wavelength converting part; and

sealing the wavelength converting part with a sealer,

wherein the quantum dot is dispersed in the dispersive medium in an undiluted liquid state without being purified after synthesis.

10 . The method of claim 9 , wherein the sealing comprises stacking first and second sealing sheets;

injecting the wavelength converting part into an area between the first and second sealing sheets; and

heating around and thermally adhering the wavelength converting part of the first and second sealing sheets.

11 - 18 . (canceled)
