Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0020] The invention discloses a nitrogen oxide fluorescent powder composition, the general formula is Ba 3-x Si 6 o 12 N 2 :Tb x , where 0.001≦x≦1, and take Tb as the emission center.

[0021] For specific implementation steps, see figure 1 , figure 1 It is a flow chart of the manufacturing method steps of the present invention, which includes:

[0022] Step S1: providing a precursor;

[0023] Step S2: using a solid-state synthesis method to sinter the precursors to synthesize oxynitride phosphors.

[0024] The precursors include barium carbonate (BaCO 3 ), silicon nitride (Si 3 N 4 ), sil...

Abstract

The invention discloses an oxynitride phosphor powder composition and a manufacture method thereof. The oxynitride phosphor powder comprises a composition with a general formula of Ba3-xSi6O12N2: Tbx (0.001<=x<=1), wherein Tb (terbium) is a light-emitting center of the oxynitride phosphor powder. Since the characteristic that light sources with different wavelengths are used as an excitation light source, thereby generating correspondingly different light-emitting colors is provided, the oxynitride phosphor powder composition can also be used for a color change-over switch or in other applications.

Description

technical field [0001] The invention relates to a composition of nitrogen oxide fluorescent powder, in particular to a nitrogen oxide fluorescent powder capable of controlling the color of light emission and a manufacturing method thereof. Background technique [0002] With the development of social civilization and the improvement of human awareness of environmental protection for energy conservation and emission reduction, countries that are currently in the leading position in the world are gradually eliminating traditional lighting equipment and replacing them with white light-emitting diodes, which are characterized by small size and can be used in conjunction with applications. Equipment adjustment, power consumption is one-eighth to one-tenth of ordinary light bulbs, one-half of fluorescent lamps, life expectancy of more than 100,000 hours, low heat generation, good response speed, and high-frequency operation, etc. , so it can be used as a new light source for lighti...
