![]() 1Zinc acetate aqueous solution add wherein.Under agitation condition, the stablizer ethylenediamine tetraacetic acid (EDTA) of adding and zinc acetate equimolar amount forms white casse liquid.Splash into 60ml 0.2molL then 1Hydrochloric acid soln to regulate pH value be 2,45 ℃ of stirring hydrolysis down.To regulate liquid pH value with ammoniacal liquor then is 5.5 60ml 0.2molL In 50ml water, add the 0.5ml tetraethoxy, use 2molL Zinc sulfide nano-material has special photoelectric property, is with a wide range of applications in fields such as luminescent material, optoelectronic equipment and LED material.The application performance of zinc sulfide nano-material is decided by its particle diameter and Surface Physical Chemistry character.Usually, the physicochemical property of zinc sulfide nano-material are very unstable, change easily in application, and it is very important therefore controlling its particle diameter and improving its stability.The method of control zinc sulfide nano-material particle diameter commonly used at present and its stability of raising is to adopt other materials to carry out the surface to coat.Coating commonly used has organic polymer and inorganic polymer (comprising silicon oxide and pottery etc.), coats back and nano particle and forms nanocomposite structures.Wherein the zinc sulfide nano mixture of silicon oxide coated modification demonstrates more and more important application prospects on modern times demonstration and luminescence technology.But the inorganic coating of zinc sulphide at present mainly is to adopt sol-gel method or laser deposition to be embedded in silica glass or the film, and cost is higher, operation inconvenience, so it has been subjected to very big restriction in Application Areas, and be unfavorable for scale operation.
