Symmetry was seen to have an effect on the observed reverse saturable absorption (RSA) response. Based on the five level model rate equation nonlinear fit of the RSA response curves and Real Time Time Dependant Density Functional Theory (RT-TDDFT) results, the singlet excited state population dynamics was found to play a significant role in producing the observed Im[γ] trend.]]> Thu 17 Feb 2022 15:40:47 SAST ]]> Singlet oxygen and optical limiting applications of BODIPYs and other molecular dyes https://commons.ufh.ac.za/vital/access/manager/Repository/vital:57238 Mon 24 Oct 2022 15:47:54 SAST ]]>
