▎ 摘　　要

NOVELTY - Preparing germanium-doped graphene material involves placing the germanium source and carbon source in distance of 0-50cm in the reaction furnace tube in molar ratio of 50:1 to 1:1000, heating to 1050-2000 degrees C at rate of 1-300 degrees C per minute under 10(-5) to 105 Pascal, introducing into protective atmosphere and reacting for 1-1000 minutes under protective atmosphere. The obtaiend product is cooled to room temperature at rate of 1-500 degrees C to obtain germanium-doped graphene material. USE - Method for preparing germanium-doped graphene material for quantum light source, photovoltaic, semiconductor device, electronic circuit, radio frequency device, integrated circuit, nanometer energy and composite material (claimed).
