摘要: In this work we tried to achieve multicolor up-conversion luminescence in low phonon energy material NaLaF4 doped with different Er3+ Tm3+ and Yb3+ concentrations. Up-conversion was measured main bands from red, green blue spectral regions were observed. The relative intensities of the could be changed by changing doping levels rare-earth ions. Changes color achieved applying infrared pump power density. coordinates depending on level as well density presented CIE (x, y) chromaticity diagram (1931).
