摘要: Abstract BaAl 12 O 19 :Tb,Ce phosphors were prepared by sol-gel technique, the crystalline structures of samples characterized XRD, and luminescence properties energy transfer between Ce 3+ Tb investigated. The results indicated that emission intensity excitation wavelength range increased when was doped. It demonstrated added in :Tb could deliver to , not luminous itself. relative at 548 nm strongest /Ce ratio 2:1, excited 310 nm, which characteristic adsorption .
