Tb3+ complex containing N,N',N"-tris(2-hydroxybenzamido) triethylamine was synthesized and its indirect upconversion sensitization luminescence was studied using two-photon excitation method. The results indicate there exist a phonon-assisted and a resonant energy transfer processes in different excitation range. Based on the result, an upconversion mechanism was proposed. Its efficiency was 1% at a pumping energy of 1.5 mJ under nanosecond pulse excitation, suggesting its potential use in display and probing.
