Embodiment

[0040] Phosphor powder preparation

[0041] Preparation of the first fluorescent powder: about 0.6 gram of imidazole (Imidazole, IMZ) compound, about 1.151 g of gram of hydrous zinc nitrate (Zn(NO 3 )2.4H 2 O), and 80 milliliters of dimethylformamide (DMF) are placed in a closed reactor, and the hydrothermal method is carried out to manufacture the first phosphor powder, wherein the temperature is raised to At about 130°C, after maintaining a substantially constant temperature for about 24 hours, it was naturally lowered to room temperature; a drying procedure was then performed to initially remove the solvent to form an organometallic complex Zn(C 3 N 2 h 4 ) 2 After the crystallization, the obtained crystal was placed in a vacuum oven at 85° C. and dried for 24 hours to obtain the organometallic complex Zn(C 3 N 2 h 4 ) 2 powder.

Abstract

The invention relates to a white light emitting device, a manufacturing method and application thereof. The white light emitting device comprises an ultraviolet light emitting diode chip, first fluorescent powder and second fluorescent powder, wherein the ultraviolet light emitting diode chip is used for generating first radiation; the first fluorescent powder consists of Zn(C3N2H4) powder and is excited through the first radiation to convert a part of the first radiation into second radiation; the second fluorescent powder is excited through the first radiation/or the second radiation to generate third radiation; and the third radiation is mixed with the first radiation and/or the second radiation to form white light. The white light emitting device can effectively brighten a white light source, because only two kinds of fluorescent powder are used, the cost is lower, and the technology for obtaining the white light by allocating the proportion of the fluorescent powder is easier.
