Abstract

We review the optical properties of bulk wurtzitic semiconductors. Reflectance and photoluminescence features are related to the crystal symmetry; selection rules for the optical process are introduced as well as the concepts of fee excitons and exciton-polaritons. The problem of the long-range Coulomb interaction in anisotropic uniaxial crystals is treated. Finally we discuss photoluminescence as an efficient tool for diagnosing doping in bulk semiconductors.
