Device for emitting light |
| abstract |
The present invention relates to a device for emitting light. In one embodiment, an LED has a nano-particle (e.g., quantum dot) coating layer over it for down-converting the light from the LED. The nano-particles are in a dispersion medium for dispersing the nano-particles. The dispersion medium is mixed with a weak acid or a salt thereof. The nano-particles may be coated with silica and the solution is pre-treated with a base or alkali-silanolate to increase the stability of the nano-particles in light conversion. |
