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

Persisten spectral hole bummg has been observed in the inhomogeneously broadened SO-S, transition of lsoln[ed perylene zmd perylene butlric acid molecuks adsorbed on various surfaces rrom vacuum .md rrom solu~mn. The measured widths 01 the specu-al holes. the vlbralmnal frequencies in the S, smte. the inhomogeneous linewidths. and Ihe Dsbye-Wailer racmrs or the adsorbed molecules are discussed in comparison with the values or the dyes embedded in amorphous polymen.

We have used persistent spectral hole-burning to investigate free-base octaethylporphine (OEP) physisorbed on y-alumina. This system combines the efficient photochemical hole-burning mechanism of free-base porphines with the idea of decoupling the chromophores from the surrounding by using surface a
We studied the photoinduced electron transfer process at low temperatures by using persistent spectral hole burning spectroscopy. The efficiency of non-photochemical hole burning for zinc tetraphenylporphine (ZnTPP) and zinc phthalocyanine decreased in the presence of electron acceptors. This is att
