A relationship is obtained between the homogeneous absorption spectrum ofan impurity centre and the hole shape burnt during the strongly inhomogeneously broadened optical transitions of impurities in solids. Model calculations show a strong dependence of the hole shape on the laser frequency and bur
Small shifts of the electronic levels of perylene in polyvioylbutyral by an electric field are probed by measuring the reversible fdling of the center of a persistent spectral hole. The experimental results are explained by a linear electriofield dependence of the level shifts which is ascribed to t
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
An optical transmission filter based on photochemical hole burning has been applied for the measurement of the resonance fluorescence spectrum of H,-octaethylporphin impurity in an amorphous polystyrene matrix in the temperature range T= 5.1 -I K. A comparison with the results of hole-burning experi
