Microstructure and growth mode of diamond films by electron assisted CVD method have been studied by means of transmission electron microscopy. The results showed that grain size in diamond film, defect and the film growth mode are different to diamond films appearing different colour. There exists two typical microstructure in crystals of different diamond films,one is mainly five-fold twins, the other is mainly dislocation and micro twins coexisting.
