  4. Abstract:
  5. The visible band (band A) of photoluminescence spectra of high-purity synthesized diamond is analyzed by the deconvolution technique. A set of eight lines with distinct peak energies are found. The peak energy and the width of these lines were either constant or varied very slightly with temperature. The amplitude of the lines are significantly temperature dependent. The closeness of the temperature at which the amplitudes of these lines reach their minimum to the temperature at which the free-exiton emission is maximum, is an indication of the competition between these two effects
