Abstract
Bi3+-activated LaAlO3:Ho3+ Phosphor, was prepared by Polyol method, and its photoluminescent properties were investigated under (UV) light excitation. Luminescence studies indicated that optimum concentration of Bi3+ and Ho3+ in LaAlO3 was found to be 1 and 1.5 at.%. The luminescent intensity of Ho3+ emission lines was remarkably enhanced on exciting with 272 nm, which suggested that efficient energy transfer from Bi3+ ions to Ho3+ ions takes place. There is significant energy overlap between the emission band of Bi3+ ions and the excitation band of Ho3+ ions.The ET efficiency has been calculated and found to be 69%. The critical ET distance has been calculated by the concentration–quenching method. The enhanced intensity and tuned luminous color of LaAlO3: Bi3+/Ho3+ phosphors from blue to cyan provides a promising material for field emission display devices.
