Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a luminescence color conversion composition, a luminescence color conversion unit, and a backlight unit using the luminescence color conversion composition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminescent color conversion composition, a luminescent color conversion unit, and a backlight unit using the luminescent color conversion composition, which convert the wavelength of blue light to generate white light.

Quantum dots are nanoscale semiconductor materials that exhibit a quantum confinement effect. The quantum dots generate stronger light in a narrow wavelength band than ordinary phosphors.

The luminescence of quantum dots is generated by the transfer of electrons excited from the conduction band to the valence band. In the case of the same material, the wavelength exhibits characteristics depending on the particle size. As the size of the quantum dots decreases, the light of a short wavelength is emitted, so that light of a desired wavelength range can be obtained by controlling the size.

The quantum dot emits when excitation wavelength is arbitrarily selected. Therefore, when there are various kinds of quantum dots, the quantum dot excites to one wavelength, and various colors of light can be observed at a time. Even if the quantum dots are made of the same material, the color of the emitted light may vary depending on the particle size. Due to such characteristics, quantum dots are attracting attention as next generation high brightness light emitting diodes (LEDs), bio sensors, lasers, and solar cell nano materials.

Currently, the production method that is commonly used to form quantum dots is nonhydrolytic synthesis. According to this method, a nucleus is formed (nuclraization) by thermal decomposition reaction by rapid injection of a metalorganic compound at room temperature as a precursor or precursor into a high-temperature solvent, and then nuclei are grown by applying a temperature to grow quantum dots Manufacturing. The quantum dots mainly synthesized by this method contain cadmium (Cd) such as cadmium selenium (CdSe) or cadmium tellurium (CdTe). However, considering the current trend of pursuing the green industry due to heightened environmental awareness, it is necessary to minimize the use of cadmium (Cd) which is one of the typical environmental pollutants that pollute water quality and soil.

Therefore, it is considered to manufacture quantum dots as a semiconductor material which does not contain cadmium as an alternative for replacing existing CdSe quantum dots or CdTe quantum dots. Indium sulfide (In ₂ S ₃ ) quantum dots are one of them.

In particular, indium sulfide (InS ₂ ) has a bulk band gap of 2.1 eV, and InS ₂ Since the quantum dot can emit light in the visible light region, it can be used for manufacturing a high-luminance light emitting diode element or the like. However, since Group 13 and Group 16 are generally difficult to synthesize, it is not only difficult to mass-produce indium sulfide quantum dots, but also has a disadvantage in that the particle size uniformity is secured and the quantum yield (QY) is poorer than that of conventional CdSe.

Therefore, the demand for the development of new quantum dots without using cadmium is increasing.

OLEDs and LCDs have strengths and weaknesses. OLEDs have excellent color reproduction performance for R (red), G (green), and B (blue) , Whereas LCDs capable of high resolution display have a problem that the RGB color reproduction power is lower than that of OLEDs. Therefore, there is a growing demand for a technique for increasing the resolution of the OLED and / or improving the coloring power and the light efficiency of the LCD.

As a result, the present inventors have made efforts to produce a new material capable of replacing quantum dots of existing inorganic materials.
