碰撞等离子体法合成聚合物非晶碳近红外光学材料
Near infra-red optical materials from polymeric amorphous carbon synthesised by collisional plasma process
摘要：
报道了用微波激发碰撞碳氢等离子体法制备类聚合物非晶碳（a-C：H）薄膜。得到稳定的和高度芳香的a-C：H含有显着的夹杂物的聚（对苯撑亚乙烯基）（PPV）。PPV赋予合成材料通用的光电性能。也就是说，具有定制折射率的a-C：H能够在可见光（红色）-近红外波长范围内变得无吸收。包括苯基簇和/或颗粒的大芳烃的产生归因于在碰撞等离子体条件下元素等离子体物质的增强凝聚。还描述了在等离子体合成过程中a-C：H中发生的详细结构和形态变化。
英文摘要：
The synthesis of polymer-like amorphous carbon (a-C:H) thin-films by microwave excited collisional hydrocarbon plasma process is reported. Stable and highly aromatic a-C:H were obtained containing significant inclusions of poly(p-phenylene vinylene) (PPV). PPV confers universal optoelectronic properties to the synthesised material. That is a-C:H with tailor-made refractive index are capable of becoming absorption-free in visible (red) - near infrared wavelength range. Production of large aromatic hydrocarbon including phenyl clusters and/or particles is attributed to enhanced coagulation of elemental plasma species under collisional plasma conditions. Detailed structural and morphological changes that occur in a-C:H during the plasma synthesis are also described.
