Abstract :

The paper reports BaMgAl10 O17 doped with Sm phosphor synthesized by solid state reaction with different concentration. The 2% Sm doped phosphor exhibit good emission at the excitation of the material with 254 nm wavelengths generates a strong emission at 367, 470, 730 nm. Besides this, subsidiary maxima at 401, 451, 484 and 497 nm wavelengths in violet region are discernible with dispersion towards green region. These changes are may be affected due to electronic charges and sizes of these added impurities.
