The surface of polyester fabrics is treated with five kinds of nano-powders(ZnO,TiO_2,SiO_2,Al_2O_3,SnO_2)with four silane-coupling agents and four titanate-coupling agents,and then the permeation rate of ultraviolet radiation and the ability of photo catalyzing of the fabric are tested.

ZnO and ZrO_2 nano-powders were prepared by Polyglycol Method,using Zn(NO_3) and ZrOCl_2 as precursors.

SnO 2 and TiO 2-SnO 2 nano-powders were prepared by stearic acid method.

MgAl2O4 spinel nanometer powders were synthesized via sol-gel process of aluminium isopropoxide that hydrated in the solution of magnesium nitrate with tetrahydrofuran being stabilizer.

The crystallization process was studied for the VO2 nanometer powders prepared by a liquid phase hydrolysis method with VOSO4 as precursor, and the physical properties of the prepared powders were tested by means of TGA, DSC, XRD and TEM in this paper.

Beginning with a brief description of the preparation and properties of rare earth compounds,thispaper compares and discusses the preparation methods and physical properties such as luminescence and catalysis of rare earth compounds nanometer powders.
