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(viny1 alcohol) (PVA) and other polymers as well as non-photochemical hole-burning of methylene blue in P
over, the method has only small memory requiremmts. Figure 4 represents the input admittance versus frequency of a stub circuit. Figure 5 ( a = 20 mm, w , = w2 = 10 mm, b = 40 mm, sx = 5 mm, I , = 28.1 mm, d = 40 mm, dl = 10 mm, F, = 10) given by WCIP is in very good agreement with [8].
Persistent spectral hole burning spectroscopy is applied to evaluate the low-temperature relaxation around the dye molecules doped in several types of polymers. The doped dye is tetraphenylporphine, and the measured polymers are vinyl polymers and main chain aromatic polymers. The changes of microsc
We comment on recent experiments on the determination of rate dispersions in hole-burning systems. We show that the fading of the fluorescence signal is not directly related to the kinetics of the hole-burning reaction.
