چکیده انگلیسی
Three potential techniques, i.e. the optical taper fiber-microsphere device(OFMD), employment of the low phonon energy tellurite glass and the optimal concentration of rare-earth ions are investigated and identified for improving the efficiency of up-conversion (UC) luminescence for rare-earth ion doped materials excited by laser. The tellurite glass with composition of 77TeO2-12Na2O-5ZnO-5La2O3 was synthesized with different Yb3+/Tm3+co-doped concentration. The OFMD with high efficiency coupling and high energy density whispering gallery mode (WGM) was constructed. By the excitation of 976â¯nm laser, the WGM resonance enhancement UC blue (475â¯nm) and red (648â¯nm) light were obtained. The WGM resonance enhancement UC luminescence mechanism, the rare-earth ions energy transfer mechanism and the optimal Tm3+ concentration were investigated.
