英文摘要	in this paper, thulium doped zro2 nanocrystals with different phases were prepared by pechini sol-gel complex method. the effects of host structure, phases and concentration on luminescence properties of tm3+ ions were investigated. with the increase of the concentration of tm3+ ions, the phosphors phase transformed from monoclinic to tetragonal structure and all the phosphors emitted blue light. however, because the environment symmetry around tm3+ in m-zro2 (c-2h) is worse than that of t-zro2 (d-4h), there were still obvious differences in the emission and excitation. the reason was investigated with the help of energy level diagram. in addition, the quenching concentration of tm3+ in zro2 host is 1 m/m%.
