Embodiment 1

[0050] Example 1. α-PbF 2 Preparation of nanorods

[0051] Example 1-1 After successively adding 50ml cyclohexane, 10ml OP emulsifier (TRITONXT-10), 6ml n-pentanol, 10ml 0.1mol / L lead acetate aqueous solution to a 100mL round bottom flask, the system was placed in Ningbo, Zhejiang In the JY92-2D ultrasonic instrument (ultrasonic frequency 20kHz) produced by Zhike Institute of Devices, at room temperature and normal pressure, the power was set to 600W, and the quaternary emulsion was prepared by ultrasonication for 10 minutes. Then, 10ml of 0.2mol / L ammonium fluoride solution containing 0.5g PEG-6000 was added and allowed to stand for 24h. The product was separated by centrifugation, the precipitate was washed with distilled water and ethanol in sequence, and the resulting precipitate was vacuum-dried at room temperature to obtain a white powder, namely α-PbF 2 Nano stave. Powder XRD results show that it is pure orthorhombic α-PbF 2 . The positions and intensities of the p...

Abstract

The present invention relates to an alpha-PbF2 nano material. It is a one-dimentional nano rod whose diameter is 100-500 nano and length is 1300-10000 nano or nano strip whose thickness is 100-160 nano, width is 500-10000 nano and length is 4500-20000 nano or nano sheet whose thickness is 100-200 nano and side lengths are 1200-1500 nano and 1200-2500 nano. The PL optical spectrum of the invented alpha-PbF2 nano material at room temperature is strong, so that it can be used for preparing fluorescent material. Its preparation method is an ultrasonic emulsion one which is created by organically-combining ultrasonic technique and microemulsion system.

Description

1. Technical field [0001] The invention relates to a new method for preparing nanometer materials—ultrasonic emulsion method and the preparation of new products α-PbF2 nanorods, sheets and strips. The new product has strong luminescent properties. Specifically, ultrasonic technology is used to form an emulsion, and then different subsequent treatments are used to prepare α-PbF2 nanomaterials with various shapes and sizes. The prepared α-PbF2 nanomaterial rods, strips and sheets have not been reported and are new products. And has a strong luminescent properties. 2. Background technology [0002] Since Gleiter et al. [See: Birringer R, Gleiter H et al. Phys Lett.1984, A(8): 365-369.] first prepared nano-blocks, the preparation and physical and chemical properties of nano-materials have become the current international One of the cutting edge research. [0003] The traditional methods of preparing nanomaterials can be generally divided into three categories: gas phase meth...
