Sol gel synthesis and optical characterization of the sralo: mn nano phosphor

Mn doped SrAlO nano phosphors were synthesized by adopting a simple Sol-Gel Method. X-Ray Diffraction (XRD) profile confirms the monoclinic nature of Mn doped SrAlO nano phosphors. The results show that SrAlO:Mn with an average particle size of 80 nm is formed. In addition, Scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS) and Fourier-Transform IR spectroscopy (FTIR) were also used to characterize the synthesized phosphor. The efficiency of the prepared phosphors was analyzed by means of its emission spectral profiles. 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.
