Fluorescent powder/glass complex applied to semiconductor lighting and preparation method thereof

The invention relates to a fluorescent powder/glass complex applied to semiconductor lighting and a preparation method thereof. The complex comprises 50 to 99.9 percent of boron aluminate glass and 0.1 to 50 percent of rare earth doped aluminate fluorescent powder in percentage by mass, and is prepared by performing hot pressed sintering at the temperature higher than the vitrification point of glass powder. The fluorescent powder/glass complex has luminous performance equivalent to that of the contained fluorescent powder, and has better forming performance, high temperature resistance and luminous stability. The fluorescent powder/glass complex can be combined with an ultraviolet light, purple light or blue light LED chip to manufacture a novel LED illuminating device which has excellent luminous stability, ultraviolet irradiation resistance and temperature stability.
