摘要
The regeneration procedure of Q-state PbS particles in lead arachidate(PbAr)Langmuir-Blodgett films have been studied by means of UV-vis absorption, FT-IR spectra and quartz crystal microbalance(QCM) measurements.The results showed that the mole fraction of PbS particles in LB films was increased by immersing PbScontaining ArH LB films in a Pb￣(2+) buffer solution,followed by being reexposed to H_2S gas.
