摘要

研究了在超临界流体中，强纳秒激光脉冲对纳米柱状氮化碳膜界面结构转变的影响。脉冲强度在4.7-12 mJ范围内变化，照射时间为5 min。已知强激光照射会产生激波，使液体变成超临界流体。当强度超过一定阈值时，薄膜表面会形成规则形状的微晶。SEM显示微晶尺寸约为1μm。光发射光谱提供了微晶中碳和氮的相对含量，这与超硬的C3 N2和C2 N化合物相似。

Impact Synthesis of Carbon Nitride Diamond-like Phases in a Supercritical Fluid

The influence of intense nanosecond laser pulses on structural transformations at the interface of the nanocolumnar carbon nitride film in a supercritical fluid is investigated. The pulse intensity was varied in the range 4.7–12 mJ, while the irradiation time was 5 min. The intensive laser irradiation is known to create shock waves turning liquid into a supercritical fluid. When the intensity exceeds a threshold, some microcrystals of regular shape are formed on the film surface. SEM revealed microcrystals of about 1μm. Photoemission spectroscopy provided the relative amounts of carbon and nitrogen in microcrystals, which are similar to those in the superhard C3 N2 and C2 N compounds.
