| Abstract: | Luminescence properties of the salicylic-RE complex have been studied. The results for salicylic-RE complex doped with Tb3+ or Tb3+/Gd3+ ions show that they are high efficiency luminescent materials. The energy transfer between salicylic radical and Tb3+ ions were observed through the measurement of excitation spectrum and emission spectrum as well as fluorescence decay time and it was quite efficient from salicylic radical to Tb3+ or Tb3+/Gd3+. The substitution of 4/5 mol Tb3+ for Gd3+ ions was obtained with satisfatory results.The following formula can be used to estimate the energy transmission efficiency between salicylic radical and Tb3+ ions: P=1/τ*-1/τ (1) η=1-τ*/τ (2) where P is energy transmission probability, η the energy transmission efficiency,and τ and τ* are decay time of sal and sal-Tb3+ respectively. |
