Abstract

The invention relates to a method for preparing a Zn3P2 nano-rod. The method for preparing the Zn3P2 nano-rod is characterized by comprising the following steps: firstly, mixture is obtained by mixing according to the fact that the mol ratio of ZnCl2 to P to NaBH4 or KBH4 is 1 to 2 to between 1 and 5 to 4 to 10; secondly, uniform rheological substances are obtained after ulstrosonic dispersion ofthe mixture in the first step in an ethylenediamine medium for 1 to 2 hours; thirdly, the rheological substances obtained in the second step are transferred into a stainless steel reaction kettle of a polytetrafluoroethylene substrate, kept a constant temperature for 4 to 7 days at a temperature of between 160 and 200 DEG C, and then are naturally cooled, and a solvent thermal product is obtained; fourthly, the solvent thermal product obtained in the third step is filtered for 3 to 5 times by utilization of ethanol, dissolved into ethylene glycol at a temperature of 80 DEG C, stirred for 1 hour at a constant temperature, and then undergoes pump filtration; and fifthly, a product after pump filtration in the fourth step undergoes vacuum drying for 6 to 12 hours at a temperature of between 80 and 100 DEG C, and the yellow-gray Zn3P2 nano-rod product is obtained. The method has a simple technique, meets the environmental requirement, does not require presintering treatment, is low in synthesis temperature, and then reduces the energy consumption and the reaction cost.

Description

technical field [0001] The invention belongs to the field of nanomaterials and nanotechnology, and in particular relates to a preparation method of Zn3P2 nanorods. Background technique [0002] In recent years, due to the increasingly serious energy problems and the attention paid to energy conversion materials, the research on the photoelectric properties of semiconductor materials has become an important hot spot. As a photoelectric material, zinc phosphide has a direct bandgap width of 1.4-1.6eV and a high light absorption coefficient (>10 4 cm -1 ) and a long light diffusion length (~13 μm). These special properties make zinc phosphide nanomaterials the best candidates for high-efficiency space light detectors, and this material is very suitable for applications in solar cells, optoelectronic devices, and lasers. In 2006, G.Z.Shen et al. used ZnS and GaP as raw materials to synthesize zinc phosphide horn-shaped nanowires by thermochemical method. The results of pho...
