Preparation of Amorphous Silicon Carbide Nanostructures via Solvothermal Method

Abstract:

A solvothermal method was developed to synthesize silicon carbide nanoflakes and nanowires through pyrolysis of polymethylsilane (PMS) at 550 °C in solution. Evidences from HRTEM, SAED, FTIR and XPS indicated that the products were amorphous nanostructures which mainly consisted of Si, C elements and trace amount O element. Owing to concrete quantum confinement effects, the unique nanostructures have strong photoluminescence centered at 410-430 nm under excitation wavelength of 350 nm
