Abstract

The ultraviolet (UV) transmission spectra of dimethylzinc (DMZn) and dimethylcadmium (DMCd) chemisorbed on quartz surfaces have been measured between 190 and 290 nm. Using chemisorption spectra obtained after different thermal pretreatments of the SiO2 substrate, it is shown that the surface hydroxyl groups play a crucial role in the chemisorption of DMZn and DMCd molecules at 300 K. Spectral changes due to thermal effects and low-power, 248 and 193 nm excimer-laser irradiation are compared and the differences are discussed.
