The values βeff (×10−5 m MW−1) using 532 nm Nd:YAG (560 nm monochromatic Ekspla) laser sources were 23.5 > 14.3 > 9.20 (14.4). The second-order nonlinear coefficient obtained using density functional theory calculations, the theoretical hyper-Rayleigh scattering (βHRS, ×10−28 esu), showed the decreasing trend for H2TPrOPhOPc (2.28) > CoTPrOPhOPc (2.10) > Mn(OAc)TPrOPhOPc (1.86). The 4-(propargyloxy)phenoxy substituents enhanced the optical limiting properties of the synthesized phthalocyanines.]]> Thu 11 Aug 2022 12:39:51 SAST ]]> Optimizing phthalocyanine based dye-sensitized solar cells: The role of reduced graphene oxide https://commons.ufh.ac.za/vital/access/manager/Repository/vital:44695 Thu 11 Aug 2022 12:37:38 SAST ]]>
