Abstract. Formation of ultrasmall particles of Pbl z in methanol was observed by means of stroboscopic stopped-flow spectroscopy. Pulse-laser induced electron transfer from Pbl z' Hgl., and Hil 3 to viologens was measured for various laser intensities and for various viologen concentrations. The electron transfer yields were 0.24, 0.08, and 0.03 for Hgl., Pbl., and Hi1 3 , respectively. The laser-intensity dependence differed from the previous observation for CdS and showed that the low yield is not attributable to the direct electron-hole recombination in the particle.
