The carbon films are prepared by r. f. plasma method with n-butylamine as carbon source. The analysis of Raman spectrosewpy
shows that this kind of carbon film has diamond-like structure, and IR spectroscopy measurement indicats that there are SP2 bonding, SP3 bonding and amino-group in the film. It is the existence of amino-group and hydrogen atom that cause the amorphous structure
and the deformation of bonding to increase, thus leading the Raman spectrum to form a broad absorption band. The quartz crystal
microbalance (QCM) deposited with this kind of carbon film as recognizing coating is very sensitive to formic acid vapors.
This QCM sensor has good reproducibility, high stability, rapid response and long lifetime. 相似文献

Silicon-phthalocyanine (SiPc) is chemically bonded to 3-aminopropltriethoxysilane (NH2(CH2)3Si(OC2H5)3, KH550) by the nucleophilic substituted reaction between the active chlorine of silicon dichlorine phthalocyanine (SiPcCl2) and amino-group of KH550. The reacted product is hybridized with 3-glycidoxypropltrimethoxysilane (CH2OCHCH2O(CH2)3Si(OCH3)3, KH560) with sol-gel processing to form sol-gel inorganic material with good physical-chemical and optical properties. Due to tethering SiPc to the network, the aggregation of SiPc is effectively prevented in sol-gel derived matrix, and the doping concentration of SiPc in the form of monomer in the matrix is greatly enhanced. The cross-linkage of SiPcCl2 and KH550 is estimated and confirmed with FT-IR spectra. The optical limiting effects (OLE) of the gel with different content of SiPc are investigated with a frequency double Q-switched Nd3+:YAG laser of 8 nsec. pulse. 相似文献
