| Popis: | Transport of energy between luminescence centers has been observed in ZnS :Cu :In phosphors at room temperature and at 77°K. The results support a photoconductive transfer mechanism. Energy transfer at low temperatures can be interpreted as resulting from a process in which a given wavelength is capable of putting an electron into an impurity level from the valence band, as well as exciting it from the same impurity level to the conduction band. |
