| Abstract: | Uniformly dispersed PbCrO_4 nano-luminescence-ellipsoidal particles were successfully synthesized with microemulsion solution of Pb(NO_3)_2 and K_2CrO_4 in quaternary warter/oil(W/O) microemulsion system containing water,Triton X-100,cyclohexane and n-pentanol.Transmission electron microscopy (TEM),X-ray diffraction (XRD) were utilized to characterize the morphology,particle size and structure of PbCrO_4,Infrared ray (FT-IR),ultraviolet (UV-Vis) and fluorescence (PL) were used to research the optical properties of products. |
