中文摘要	several three-dimensional (3d) hierarchical architectures of lu2o2s:eu3+ have been successfully synthesized via a simple solvothermal method with polyvinylpyrrolidone (pvp) as surfactant, followed by a subsequent calcination process. the as-prepared products were well characterized by means of x-ray diffraction (xrd), fourier transform infrared (ft-ir), scanning electron microscopy (sem), transmission electron microscopy (tem), high-resolution transmission electron microscopy (hrtem), selected area electron diffraction (saed), and photoluminescence (pl) spectra. the results reveal that the morphologies of precursors can be tuned by altering ph value of the reaction system. detailed investigation indicates that the formations of different micro-structures are dominated by different growth mechanisms. the as-formed precursors could transform into lu2o2s:eu3+ with their original hierarchical structures maintained. under ultraviolet (uv) excitation, the lu2o2s:eu3+ micro-architectures exhibit strong red emission corresponding to the d-5(0)-> f-7(2) transition of the eu3+ ions. furthermore, the dependence of lu2o2s:eu3+ luminescence performance on different morphologies has been involved in the present work.
