A ns-pulsed argon atmospheric pressure plasma jet (APPJ) was studied for the fast desorption of weakly volatile organic molecules (bibenzyl) deposited on glass substrates at variable electric potential (floating-potential or grounded). The experiments focused particularly on thin resistant bibenzyl films (a large thick bibenzyl deposit was also studied), which are more difficult to be desorbed when using a substrate at a floating-potential. The APPJ was probed by means of high-resolution laser absorption spectroscopy to map the Ar(1s 5 ) metastable absolute density (spatially and temporally resolved) at the close vicinity of the glass plate where bibenzyl was deposited. Furthermore, the electrical, optical and thermal features of the APPJ were investigated systematically. In this way, the plasma desorption efficacy on thin resistant bibenzyl deposits was evaluated for the envisaged application, by varying the exposure time of the molecules to the APPJ ( t exp

ns脉冲氩等离子体射流用于以可变电势快速解吸沉积在玻璃基板上的弱挥发性有机化合物的实验研究

研究了ns脉冲氩大气压等离子体射流（APPJ），用于以可变电势（浮动电势或接地）快速解吸沉积在玻璃基板上的弱挥发性有机分子（联苄）。实验特别关注于耐薄的联苄薄膜（也研究了厚的联苄沉积物），当使用浮置电位的底物时，难于解吸。通过高分辨率激光吸收光谱法对APPJ进行探测，以在沉积联苄基的玻璃板附近绘制Ar（1s 5）亚稳态绝对密度（在空间和时间上分辨）。此外，系统地研究了APPJ的电，光和热特性。通过这种方式，
