The invention provides a low-temperature co-fired
ceramic material emitting
white light and a preparation method thereof. The
ceramic material comprises the following components in percentage by mol: 10 to 20 percent of CaO, 20 to 30 percent of B2O3, 50 to 60 percent of SiO2, and 1 to 9 percent of optical activating agent ions. The invention also relates to the preparation method of the material, namely, a
sol-
gel method for preparing the low-temperature co-fired
ceramic material emitting
white light. The invention has the advantages that: 1, the preparation process is simple and advanced, the
sintering temperature is low by adopting the
Sol-
gel method and is between 800 DEG C and 900 DEG C, the
sintering shrink rate at the temperature is controllable between 13 percent and 17 percent, and a
glass ceramic material has a flat and
smooth surface, as well as higher strength; 2, the
dielectric constant is adjustable between 4(1MHz) and 6 (1MHz), and the coefficient of
dielectric loss is lower than 0.002; 3, the
light emission intensity is high, the material can emit yellow and
blue light under activation of
ultraviolet light with the
wavelength of between 320nm and 410nm, the
white light obtained by mixing the
blue light and the yellow light can be used for illuminating and displaying; and 4, based on the advantages, the low-temperature co-fired ceramic material can be applied to the fields of white light LED (
Light Emitting Diode) lamps, integrated ceramic substrates and other electronic devices and semiconductors, as well as microelectronic packaging materials.
