We report the growth of carbon dioxide (CO) whiskers at low temperatures (-70 °C to -65 °C) and moderate pressure (4.4 to 1.0 bar). Their axial growth was assessed by optical video analysis. The identities of these whiskers were confirmed as CO solids by Raman spectroscopy. A vapor-solid growth mechanism was proposed based on the influence of the relative humidity on the growth.

我们报道了在低温（-70°C至-65°C）和中等压力（4.4至1.0巴）下二氧化碳（CO）晶须的生长情况。通过光学视频分析评估了它们的轴向生长。通过拉曼光谱证实这些晶须为CO固体。基于相对湿度对生长的影响提出了气-固生长机制。
