| titleOfInvention | Preparation method of pyrite-type ferrous disulfide nanoscale single-crystal semiconductor material |
| abstract | The invention relates to a preparation method of a pyrite-type ferrous disulfide nanoscale single-crystal semiconductor material. The preparation method comprises the following steps that 1, an iron source and trioctylphosphine oxide are mixed; and the mixture is dissolved in oleylamine, then is stirred and is filled with argon or nitrogen so that oxygen is removed and an iron source precursor is obtained; 2, the iron source precursor is heated in an oil bath with stirring so that an iron source solution is obtained; 3, a sulfur source is dissolved in oleylamine, then is stirred and is filled with argon or nitrogen so that oxygen is removed and a sulfur source solution is obtained; 4, the sulfur source solution is heated, then is extracted by a needle tubing and then is fast injected into the iron source solution; the oil bath for heating the iron source solution is heated; and the mixed solution undergoes a reaction to produce pyrite-type ferrous disulfide colloid; and 5, the pyrite-type ferrous disulfide colloid is cooled to a room temperature and then is added with a trichloromethane-ethanol mixed solution; the mixture is subjected to washing and centrifugation until an upper centrifugate is colorless; and the washed sample is sealed in a chloroform solution. The pyrite-type ferrous disulfide nanoscale single-crystal semiconductor material obtained by the preparation method has uniform particle sizes and morphology, and stable quality. The preparation method has good repeatability. |
