Dy doped SrAlO nano phosphors were synthesized by adopting a simple Sol-Gel Method. X-Ray Diffraction (XRD) profile confirms the monoclinic nature of Dy doped SrAl4O7 nano phosphors. The results show that SrAlO: Dy with an average particle size of 60 nm is formed. Crystalline structure of the nano particles was studied by Scanning electron microscopy (SEM). We also observed a rich IR emission from the prepared phosphors under a Ultra-Violet (UV) source. Such luminescent powders are expected to be applied as IR sensor and MRI device applications. The efficiency of the prepared phosphors was analyzed by means of its emission spectral profiles.
