Abstract
The influence of stoichiometric deviations and Sn (IV) or K doping on the optical properties of cc-mercuric iodide have been investigated. I n defect samples, a decrease in the energy gap is observed. Photolumin escence was performed as a function of temperature while samples were under uniaxial pressure. Differences between doped, non-stoichiometric and 'pure' samples are observed for the luminescent emission position and intensity.
