Blue,green and red up-conversion luminescence at around 490,545 and 650 nm,which result from the Ho~(3+):~5F_3(?)~5I_8,(~5F_4,~5S_2)(?)~5I_8 and ~5F_5(?)~5I_8 transitions,respectively,were observed in Nd~(3+)-Ho~(3+) co-doped oxyfluorotellurite glasses under 800 nm excitation.Among these up-conversion luminescence,the green emission was extremely strong and the blue and red emission intensities were very weak.Selectively strong green up-conversion luminescence of these glasses indicate a high… CONTINUE READING
