ABSTRACT:
An object of the present invention is to provide fluorescence showing a peak wavelength of excited spectrum within the wavelength range of from 350 to 500 nm and suitable for a white LED emitting yellow light, and a white LED comprising this fluorescence. This object achieved by phosphor for white. LED comprising a silicate fluorescent material and a borate fluorescent material.
