University of the Ryukyus}, month = {Mar}, note = {The quantum yield for the oxidation of Fe^<2+> induced by the photoionization of 4-ethylphenol (EP) was measured in various media such as water, SDS, DTAB and Brij 35 micellar solutions as a function of the excitation wavelength. The largest value was observed in SDS solutions and the smallest one in DTAB solutions at all excitation wavelength studied. Brij 35 and aqueous solutions gave the intermediate values. The quantum yield was found to have a constant value at the wavelength ranging from 290 nm down to 255 nm. It increased at wavelength below 240 nm. The corresponding phenomena were observed for the relative fluorescence quantum yield of EP; i.e., the fluorescence yield was constant in the wavelength region from 290 nm to 255 nm and decreased for the shorter wavelength., 紀要論文}, pages = {37--46}, title = {4-エチルフェノールの光イオン化に対するミセルと励起波長の効果}, year = {1985} }
