Mixed-Metal Cluster Chemistry. 30. Syntheses and Optical Limiting Properties of Cluster-Containing Oligo- and Polyurethanes
出版 2007“...Some insight into the mechanism by which these clusters function as optical limiters has been gleaned from complementary pump−probe studies, with their behavior consistent with a fast nonlinear absorption process followed by reverse saturable absorption involving metastable excited states of greater than nanosecond lifetime....”
