Description
Technical field
The present invention relates to prepare the method for Cadmium Sulfide-silicon dixoide nucleocapsid structure.
Background technology
Nucleocapsid structure is because its particular structure, optics and surface properties are coating, electronics recently, and fields such as photonics, medicine transmission, catalysis have obtained using widely.Photonic crystal is the artificial microstructure that can be compared with optical wavelength by its cycle that the material with differing dielectric constant (specific refractory power) is arranged according to certain spacial ordering.As " optical semiconductor ", photonic crystal has the function of unique adjusting light spread state, and, fields such as photon integrated, optical communication integrated at photoelectricity have boundless application prospect.The three-D photon crystal that is obtained by the nucleocapsid structure self-assembly has also obtained investigator's extensive interest in recent years.Because nuclear is different with the specific refractory power of shell material, can regulate the position of photon band gap by the size that changes nuclear and shell.Theoretical Calculation show by nucleocapsid structure form the photon band gap characteristic of photonic crystal be different from the photonic crystal that obtains by the self-assembly of homogeneous ball.
Cadmium Sulfide (CdS) is that a kind of very important II-VI family has direct wide bandgap semiconductor materials, is widely used in electronics, optoelectronic areas.Because this material has high relatively specific refractory power, absorb superior optical properties such as less at visible region, also be widely used in the photonic material field in recent years.The nucleocapsid structure relevant with Cadmium Sulfide, existing investigator prepares as nucleocapsid structures such as Cadmium Sulfide-polystyrene spheres, Cadmium Sulfide-Cadmium telluride fine powders.Have the people to prepare the composite structure that Cadmium Sulfide is coated on the silica spheres surface by the unit molecule presoma recently, but the composite structure that this method obtains is not single dispersion, occurs the impurity cohesion easily, and the surface coating is inhomogeneous, the thickness of shell wall is uncontrollable.
Summary of the invention
The objective of the invention is in order to obtain Cadmium Sulfide by high refractive index is that the silica spheres of shell and low-refraction is single distributed nuclei shell structure that nuclear is formed, provide a kind of cheap efficient, simple preparation coats evenly, the method for the monodisperse CdS-silicon dixoide nucleocapsid structure of controllable thickness.
The method for preparing monodisperse CdS-silicon dixoide nucleocapsid structure of the present invention, employing be chemical bath deposition, may further comprise the steps:
1) the uniform monodisperse silica sphere particle of particle diameter is dispersed in the deionized water solution with sonic oscillation, adding concentration is that the Trisodium Citrate of 0.01～0.5 mol is done network and agent, hydramine is a tensio-active agent, and regulate pH value to 8～13 with ammoniacal liquor, 50 ℃～90 ℃ constant temperature magnetic agitation, add Cadmium chloride fine powder and sulphur urine then, the concentration that makes Cadmium chloride fine powder in the solution is 0.001 mol～0.01 mol, the concentration of sulphur urine is 0.002 mol～0.02 mol, reacted 1～3 hour, and obtained the nucleocapsid structure suspension of Cadmium Sulfide parcel silica spheres;
2) add the ultra-sonic dispersion wash cycles with deionized water and dehydrated alcohol centrifugal deposition, remove reaction residue, oven dry obtains the monodisperse CdS hollow ball.
Monodisperse silica sphere particle can be commercially available or by " Si Tuobu (St ber) method " preparation, particle diameter is that 10nm is to 1000nm among the present invention.Said particle diameter is meant that evenly relative standard deviation is less than 10%.Said hydramine can be the trolamine or the diethanolamine of commercially available acquisition.
The inventive method can be regulated the radius of the nuclear of nucleocapsid structure by changing the particle diameter of silica spheres; Change the amount of Trisodium Citrate and hydramine adding and the speed that concentration is regulated Cadmium Sulfide coated silica core; Change the concentration of Cadmium chloride fine powder and sulphur urine, can regulate the thickness of shell.
Method of the present invention is nuclear with the monodisperse silica sphere particle, and silica spheres is compared with other materials and can high temperature heat-resistant be handled, and has more stability.By adding hydramine, down auxiliary at hydramine, chemical bath deposition in the alkaline aqueous solution obtains wrapping up the nucleocapsid structure of even no unnecessary Cadmium Sulfide particle and impurity cohesion, and method is with low cost, the process simple controllable.Monodisperse CdS-silicon dixoide nucleocapsid structure that the present invention makes can be used as structural motif, self-assembly prepares three-D photon crystal, absorb advantages such as few owing to the high refractive index of Cadmium Sulfide with at visible region, can strengthen the photon band gap characteristic of this structure, the radius of nuclear that can also be by changing nucleocapsid structure and the thickness of shell are regulated the residing position of photon band gap.
