摘要： A white light-emitting device comprising a blue-violet or blue LED and a phosphor material capable of emitting a yellow-green to orange-yellow light upon excitation by the light emitted by the LED. The light from the LED and the phosphor material are mixed in an appropriate ratio to produce a white light. The phosphor material has a general formula (YxMyCez)Al5O12, where x+y=3, x, y≠0, 0.5>z>0, and M is selected from the group consisting of Tb, Lu, and Yb, with (YxMy)Al5O12 serving as a host and Ce as an activator. By changing the composition of the metal elements in the host, the crystal field is modulated to thereby alter the energy level of the excited state to which the activator is transferred upon irradiation by a specific wavelength of light, leading to the change in the emitting wavelength of the phosphor material.

摘要： A method for manufacturing white light source includes the steps of providing an ultra-violet light as radiation source; and preparing two kinds of phosphors each receiving the ultra-violet light and emitting light of different wavelength. One phosphor is designated to emit light covering two wavelength regimes of three primitive colors, i.e., red light (585-640 nm), green light (500-570 nm) and blue light (430-490 nm), and another phosphor is designated to emit light covering remaining wavelength regime of the three primitive colors. The phosphors are mixed in predetermined ratio such that the lights of different wavelength are combined to provide a white light.

摘要： A manufacturing method for white light source utilizes an ultraviolet light source and suitable phosphors. One of the phosphors is directly excited by the ultraviolet light source and generates a radiation with longer wavelength. Other phosphors are excited by the radiation with longer wavelength and generate radiation with much longer wavelength. The lights generated by those phosphors are mixed to form a white light.
