摘要：

Marked frequency dependence of the quantum efficiency for hole formation was observed at 4 and 20 K for photochemical hole-burning of free-base tetraphenylporphin (TPP) and sulfonated TPP in poly(vinyl alcohol) (PVA) and other polymers as well as non-photochemical hole-burning of methylene blue in PVA. The quantum efficiency of hole formation at the lower-frequency foot of the lowest-energy absorption band is about 10 times larger than that at the higher-frequency foot, which could be due to the existence of several vibronic states in the lowest-energy absorption band with different molar extinction coefficients, hole formation efficiencies, and/or Debye-Waller factors.
