Relative hole burning efficiencies of resorufin in ethanol-2,2,2&fluoroethanol (TFE) and TFE-hydroxyl deuterated ethanol ( EtOD) mixed glasses as a function of the mole fraction of TFE are reported. The hole burning efficiency is found to increase in both mixed glass systems, with a greater increas
Spectral holes have been burnt in the S r +-Se O-O transition of resorufin in two phases of ethanol glass between 0.3 and 4.2 K. The holewidths differ by a factor of 8 and follow a T '.3 dependence. The homogeneous linewidths (r,,,) in one of the phases are about half those derived from a photon-ech
The mechanism of phosphorescence hole burning of coronene embedded in a glassy matrix is investigated. We find a linear relation between the phosphorescence hole burning rate and the incident light intensity. This supports the single photon hole burning process in contrast to a photon gated process
