説明

<jats:title>Abstract</jats:title> <jats:p>Silicon nanocrystals have been produced successfully by using silicon monoxide as the starting material via a simple solvothermal preparation method. The temperature needed in the solvothermal preparation is found to be as low as 220 °C when ethylenediamine is used as the solvent. The as-prepared silicon samples are of single-crystal nature with diameters around 5 nanometers and dispersed in an amorphous silica. The silicon nanocrystals became a little larger in size after removing the amorphous silica, according to the results of transmission electron microscope (TEM) characterization.</jats:p>
