Glass fluorescent ceramic, preparation method thereof and wavelength conversion device
The invention discloses a glass fluorescent ceramic, a preparation method thereof and a wavelength conversion device, the glass fluorescent ceramic comprises a phosphor, a glass packaging body and pores, the pores account for 20-40vt% of the glass fluorescent ceramic, the pore size of the pores is 0.6-2mu m, the phosphor accounts for 40-50vt% of the glass fluorescent ceramic, the pore size of the pores is 0.6-2mu m, and the pore size of the glass packaging body is 0.6-2mu m. And the proportion of the glass packaging body is 10 to 40 vt%. The specific air holes are formed in the glass fluorescent ceramic, so that the light scattering capability can be improved, the mixing uniformity of excited light and excited light after excitation is improved, and the problem that a yellow light ring exists when a laser light source achieves an illumination function is effectively solved; when the glass fluorescent ceramic is used for carrying out wavelength conversion on laser, obtained light spots are good in uniformity, and the luminous flux and the illumination are high.
