用激光溅射-分子束技术研究了气相中Cu的等离子体与乙醇分子团簇的反应.观察到三种团簇正离子Cu+(C2H5OH)n、CuO+(C2H5OH)n、H+(C2H5OH)n和三种团簇负离子(C2H5OH)nC2H5O-、(C2H5OH)n(H2O)OH-、(C2H5OH)n(H2O)2OH-(n≤12).详细考察了在不同的载气压力下激光烧蚀等离子体作用于脉冲分子束,以及在一定的压力下等离子体作用于分子束不同位置时,对团簇产物种类和团簇尺寸大小的影响.分析了Cu+(C2H5OH)n、CuO+(C2H5OH)n、H+(C2H5OH)n、(C2H5OH)nC2H5O-、(C2H5OH)n(H2O)OH-、(C2H5OH)n(H2O)2OH-等团簇的产生机理.
The reaction of Cu plasma with ethanol molecular clusters was studied by laser sputtering-molecular beam technique. Three cluster positive ions Cu + (C2H5OH) n, CuO + (C2H5OH) n, H + (C2H5OH) n and Three clusters of negative ions (C2H5OH) nC2H5O-, (C2H5OH) n (H2O) OH-, (C2H5OH) n (H2O) 2OH- (n≤12) were investigated in detail under different carrier gas pressures And the effect of plasma on the pulsed molecular beam and the size of cluster product when the plasma acts on different positions of the molecular beam under a certain pressure.The effects of Cu + (C2H5OH) n, CuO + (C2H5OH) n, The generation mechanism of (C2H5OH) nC2H5O -, (C2H5OH) n (H2O) OH -, (C2H5OH) n (H2O) 2OH -
