Abstract :

 Dy doped strontium aluminate phosphor (SrAl4O7:Dy) was synthesized by Sol Gel method. The influence of varied concentration of Dy on crystal structure and optical properties is analyzed by means of X–ray diffraction (XRD), Scanning electron microscopy (SEM) Photoluminescence (PL) spectra. XRD patterns reveal a dominant phase characteristics of the monoclinic SrAl4O7 compound and the presence of dopants having uncognizable effect on the basic crystal structure of SrAl4 O7 . From XRD studies, the average particle size of SrAl4 O7 : Dy phosphors is calculated to be nearly 80 nm. The results indicate that the peak positions in the spectra are not much affected by varying concentration of Dy
