A light emitting diode. The light emitting diode comprises a lead frame and an LED chip therein. Packaging material in the lead frame is covers the LED chip. A plurality of ZnX quantum dots dispersed in the packaging material, wherein X is S, Se, Te or a combination thereof. A plurality of organic molecules covers each ZnX quantum dot.

Light emitting diode

A white-light LED with omni-directional reflectors includes an LED chip for emitting white-light. A light transmitting material surrounding the LED and phosphor grains is dispersed in order to excite fluorescence via emission of LED. Two omni-directional reflectors are implemented on the top and/or bottom of the LED symmetrically surrounding the light transmitting material and the LED chip. The light from the LED was reflected omni-directionally, via the dielectric omni-directional reflectors, to increasing the efficiency and/or spectral characteristics and uniformity of the visible light emission.
