WHITE LIGHT EMITTING DEVICE, FLUORESCENT BODY AND FABRICATING METHOD THEREOF TO EFFICIENTLY FORM WHITE LIGHT OF ARBITRARY COLOR TEMPERATURE AND STABLY OBTAIN WHITE LIGHT WITHOUT VARYING COLOR TONE WITH RESPECT TO VARIATION OF TEMPERATURE

摘要

PURPOSE: A white light emitting device is provided to efficiently form white light of an arbitrary color temperature and stably obtain white light without varying a color tone with respect to a variation of temperature by using a white light emitting device and a fluorescent body. CONSTITUTION: An LED(light emitting diode) is prepared. A fluorescent body ZnSxSe1-x(0x1) is excited by the light emitted from the LED and emits light, including at least one of Cu, Ag or Au. The fluorescent body may be ZnSxSe1-x(0.2=x =1) that is excited by the light with a wavelength of 380-500 nanometers such that the light is emitted from the LED to emit light.
