A series of red phosphors Ca10Li （PO4）7：Eu3＋ were synthesized by high temperature solid-state reaction method. Their luminescence properties were characterized by means of photoluminescence excitation and emission spectra,CIE chromaticity and quantum efficiency. Results indicated that the phosphors co.ld be effectively excited by the near ultraviolet （NUV） light （393 nm）. The main emission peaks of the phosphor were ascribed to the transition 5D0–7F2 （613 and 617 nm） of Eu3＋ ion when samples were excited by 393 nm. The CIE chromaticity （x,y） of Ca9.9Li （PO4）7：0.10Eu3＋ was x=0.638,y=0.361 and the quantum efficiency of this phosphor was 75% excited by 393 nm. Therefore,this phosphor co.ld be a promising red co.ponent for the applications in white LEDs.

The extraction ability of palladium(Ⅱ) from acidic media with cyclic sulfoxide derivatives-α Dodecyl tetrahydrothiophene 1 Oxide (DTMSO), α octyl tetrahydrothiophene 1 Oxide (OTMSO) and α butyl tetrahydrothiophene 1 Oxide (BTMSO) was investigated. The extracting efficiency of cyclic sulfoxide derivatives decreased with the increasing of acidity in the lower acidity, and the efficiency became stable with the change of acidity in the higher acidity. The extraction reaction of palladium(Ⅱ)with DTMSO is exothermic, and extraction reaction of palladium(Ⅱ)is endothermic when OTMSO or BTMSO were used as extracting reagents. The co.rdination number was studied by slope method. The results indicate that co.rdination number is 2, and the co.position of co.plex is (PdCl 2)·2RTMSO. FT IR spectra were used to analyze the structure of co.plex and co.rdinated atom in co.plex, Pd is co.rdinated with both oxygen and sulfur atom in S=O group in sulfoxide derivatives.

In this study, the effect of annealing temperature on the impact toughness of β-nucleated polypropylene random co.olymer（PPR） and ethylene-propylene-diene terpolymer（EPDM） blends was investigated by differential scanning calorimetry（DSC）, wide-angle X-ray diffraction（WAXD）, dynamic mechanical analysis（DMA） and scanning electron microsco.y（SEM）. Interestingly, the impact strength of β-PPR/20 EPDM blend annealed at 120 ℃ is 1.8 times as high as that of unannealed samples. In addition, the crystalline structure, the relaxation of chain segments and fracture morphology of β-PPR/EPDM blends were also investigated to explore the toughening mechanism related to annealing. The results show that annealing at moderate temperatures results in the improvement of integrity of the crystal structure and the relative co.tent of β-phase. The work provides a possible method to toughen the semicrystalline polymer at low temperatures by annealing.
