The invention provides a light emitting diode device and a fabrication method thereof. The device comprises a pair of electrodes and one of which is electrically contacted with a holder, an LED chip fixed in the holder, a wrapping material formed in the holder and covering the LED chip, and a plurality of nanocrystals having a quantum dot state dispersed in the wrapping material. The nanocrystals satisfy the formula, ZnCdS and 0&#x3c;x&#x3c;1, and can produce a luminous wavelength of about 400 nm to 800 nm. The device further comprises a plurality of organic molecules bonded to the surface of the nanocrystals. Because a molecular interaction occurs between the organic molecules and the wrapping material, the nanocrystals are uniformly dispersed in the wrapping material to improve luminous uniformity. Furthermore, the wrapping material can protect the nanocrystals from oxidation to avoid efficiency decaying.

Light emitting diode device and fabrication method thereof

The invention provides a preparation method of ZnCdA quantum dot capable of emitting white light, in which A is S or SSe; 0&#x3c;x&#x3c;1 and 0&#x3c;y&#x3c;1. The method includes preparing a sulfur-containing organic solution; mixing a zinc-containing precursor and a cadmium-containing precursor with an organic acid, and dissolving them in a co-solvent to obtain a homogeneous solution; and mixing sulfur-containing organic solution with the homogeneous solution to produce ZnCdA quantum dot.
