Single-molecule linewidths of terrylene in incommensurate biphenyl: Thermocycling and time-resolved experiments
(2007) In Journal of Luminescence 127(1). p.218-223- Abstract
- The purely electronic linewidth delta of terrylene impurity molecules in monocrystalline biphenyl is studied at temperatures T between 1.7 and 3.5 K using the technique of single-molecule spectroscopy (SMS). Based on the data obtained, individual molecules appear to have their own law of delta(T) dependence; further, hysteresis effects have been observed in thermocycling experiments. The single-molecule (SM) lines investigated quickly broaden and vanish at temperatures between 3 and 3.5 K and reappear after the sample is cooled down again. At T approximate to 2 K, a slow process of spectral diffusion (SD) was observed on timescales longer than 10s. To learn about the role of faster SD processes, the technique of intensity time-frequency... (More)

At T approximate to 2 K, a slow process of spectral diffusion (SD) was observed on timescales longer than 10s. To learn about the role of faster SD processes, the technique of intensity time-frequency correlation (ITFC) SMS was applied to a stable SM line after it had been broadened by 75% as a result of a thermocycling experiment. At 2 and 2.3 K, no significant line broadening could be revealed on timescales between 0.16 ms and 10s. (C) 2007 Elsevier B.V. All rights reserved. (Less)
