Near infrared optical materials from polymeric amorphous carbon

摘要

The synthesis of polymerlike amorphous carbon u0002a-C:Hu0003 thin-films by microwave excitedncollisional hydrocarbon plasma process is reported. Stable and highly aromatic a-C:H werenobtained containing significant inclusions of polyu0002p-phenylene vinyleneu0003u0002PPVu0003. PPV confersnuniversal optoelectronic properties to the synthesized material. That is a-C:H with tailor-madenrefractive index are capable of becoming absorption-free in visible u0002redu0003-near infrared wavelengthnrange. Production of large aromatic hydrocarbon including phenyl clusters and/or particles isnattributed to enhanced coagulation of elemental plasma species under collisional plasma conditions.nDetailed structural and morphological changes that occur in a-C:H during the plasma synthesis arenalso described. © 2010 American Institute of Physics. u0004doi:10.1063/1.3431292
