Detection of excited state absorption cross-section of porphyrin through cw and femto-second laser pump-probe technique [PDF]
arXiv, 2019 We report on direct detection of excited states absorption cross-section using dual wavelength pump-probe technique. Also, we experimentally demonstrate using porphyrin composite molecules (porphyrin derivatives such as 5,10,15,20-meso-tetrakis phenyl porphyrin (H2TPP), 5,10,15,20 - meso-tetrakis(4-hydroxyphenyl) porphyrin (H2TPP(OH)4)).
