Surface structure and spectroscopie properties of fluorinated diamond materials

Résumé

Depending on the surface termination, the electronic properties of diamond materials can be varied over a wide range. It is well known that fluorination generates a highly hydrophobic and lubricating surface. The strong electron-withdrawing nature of fluorine bound to carbon atoms plays a role when considering the effect of surface fluorination of diamond as a means to tune its optical and electronic properties. For submicron diamond particles, several methods including the thermal gas phase fluorination, the fluorination including XeF2 and the grafting of perfluorinated alkyl moieties have been reported. Using the reported wet-chemical fluorination technique, it is now possible to fluorinate all kinds of diamond materials in a mild and highly efficient way enabling the production of functional diamond materials for applications in catalysis, tribology or medicine.
