Abstract
The effects of changes in hydrostatic pressure between 1000 and 3500 atm and temperature changes between 90 and 300 K on the fundamental optical-absorption edge and the first three exciton peaks in lead iodide were studied. Values of the deformation potential for these structures were calculated. Arguments that the excitons are centered about the cation are presented.Keywords
