Abstract
⺠Novel Dy3+ activated X6AlP5O20 (where X=Sr,Ba,Ca and Mg) phosphors were prepared by combustion method which is very low cost and time saving synthesis method. ⺠The excitation spectra of the phosphors are broad band extending from 340 nm to 400 nm, which is characteristics of NUV excited LED. ⺠PL emission spectra show two emissions (485 and 573 nm) and X6AlP5O20 :Dy3+0.5 mol% (where X=Sr,Ba,Ca and Mg) phosphors shows strongest PL emission intensity. ⺠SEM analysis indicates that phosphor particles have irregular shape, porous morphology and less than 3-4 μm in size, which is suitable for the solid state lighting (coating purpose).
