Formation of ultrasmall particles of PbI 2 in methanol was observed by means of stroboscopic stopped‐flow spectroscopy. Pulse‐laser induced electron transfer from PbI 2 , HgI 2 , and BiI 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 HgI 2 , PbI 2 , and BiI 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.
