Sol–Gel Derived Blue–Emitting Sralo:mn,Dy Nano–Phosphors

G. Suresh, V. T. Jisha

Abstract :

Blue–emitting divalent Dy, Mn activated strontium aluminate (SrAlO :Mn,Dy) phosphor were synthesized by Sol–Gel method using Strontium Acetate, Aluminum Nitrate as raw material and 2–methoxyethanol as complexing agent. The morphology, composition and structure were characterized by scanning electron microscopy (SEM), energy dispersive X–ray (EDS) and X–ray diffraction (XRD) respectively. The nanomaterials emit blue luminescence with a peak wavelength at 402 nm and 460 nm under near–ultraviolet excitation at 360 nm. The Dy and Mn doping can decrease the amount of defects, which leads to the suppression of luminescence intensity
