Abstract: A blue phosphor based on calcium strontium magnesium silicate is provided to obtain spherical micropowder having a micrometer size, showing a high absorption peak in a long UV range of 380-420 nm, and useful for a high-efficiency blue phosphor in a UV light emitting diode. A blue phosphor based on calcium strontium magnesium silicate is represented by the formula of (Ca1-xSrx)(1-y)Mg3Si4O12 : Eu2+y, wherein 0
