Fe Impurity

CaB 6 single crystals were synthesized by the Al flux method and the Fe -impurity concentration in the crystal was measured using the PIXE method. As a result, we found that the amount of the Fe impurity, included in a CaB 6 powder sample used as a starting material, is drastically reduced after the synthesis process. Lightly La doped CaB 6 single crystals were also synthesized and the La concentration was determined by PIXE.

Exciton Absorption Band

Photoluminescence of pentacene single crystals is studied in the temperature range of 7 K to 200 K under excitation with He-Ne laser light. Photoluminescence spectra consist of four broad bands, L1 to L4. The highest energy band, L1, located close to the lowest exciton absorption band mainly appears for //b-polarization. The intensity of the second one, L2, with Stokes-shift of about 1500 cm -1, decreases as temperature rises above 30 K and disappears at 100 K. The bands, L3 and L4, which are located at lower energy, are observed at higher temperatures up to 200 K. Based on their energy positions, the band L2 is assigned to a shallow self-trapped exciton luminescence band, and the bands L3 and L4 to deep self-trapped exciton luminescence bands. By comparing this result with reported result on tetracene crystals, self-trapped excitons are considered to be more stable in pentacene.
