In this paper we report the combustion synthesis of rare earth (RE=Eu, Dy) doped Ba 4 Al 2 O 7 phosphors. Prepared phosphors were characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), CIE color co-ordinates and their photoluminescence (PL) properties were also investigated. In case of Ba 4 ...
The preparation of NaCaPO 4 doped with rare earth (RE) ions Ce 3+ , Eu 3+ and Dy 3+ by combustion method was described. Under UV excitation (251 nm) of NaCaPO 4 :Ce 3+ showsd emission (367 nm) in UV range. When NaCaPO 4 :Dy 3+ phosphor was excited at 349 nm, the emission spectrum showed intense bands at 482 nm (blue) and 576 nm (yellow)...
