Effective nonlinear absorption coefficient, β eff , of solutions of some rare earth substituted phthalocyanines (viz: Sm(Pc)2, Eu(Pc)2 and LaPc) was measured using open aperture Z-scan technique under nanosecond pulse excitation at 532 nm. The effect of nonlinear absorption on optical limiting in these samples was also investigated. Both nonlinear absorption and optical limiting phenomena in these samples are attributed to sequential two-photon absorption (STPA) process.

For producing RGB tricolor luminescence, three kinds of components of rare-earth ions is chosen, which are Er3+doping, Er3+-Yb3+co-doping and Tm3+-Yb3+co-doping, respectively. Three kinds of rare-earth doped up-conversion fluoride material are prepared based on high temperature solid-state method. Under being excited by 980nm laser, three materials emit red, green and blue light, whose peak wavelengths are 660nm, 550nm and 480nm, respectively. Through analysis of luminescence process, it can be concluded that red and green luminescence are belong to two-photon absorption transversion, and blue luminescence is three-photon absorption transversion.
