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
A new burn-probe sequence is utilized uith non-photochemical hole burning to study the optical dephasing of impurities in polymer films. For crcsyl violet in pol)?inyl alcohol the temperature dependence of dephasing is close to linear in the range studied. A burn time dependence of hole widths is ob
