Using argon-ion laser excitation, luminescence has been observed at low-temperature (14K) in the region between 17500 and 20000 cm(-1), for single crystals of cobalt(II)-doped KCdBr3. This luminescence is assigned to transitions from the lowest energy component of the T-2(2g)(H) state, (2)A " in the C-5 point symmetry of the cobalt(II) site, into the T-4(1g)(F) ground state manifold. It gives rise to two broad bands with sharp origins at 20029 and 19127 cm(-1) upon which is superimposed considerable vibronic structure. This is believed to be the first example of luminescence detected from the T-2(2g)(H) state of the cobalt(II) ion. However, as the intensity drops markedly between 14 and 70 K, this transition is not a suitable candidate for the investigation of laser action. Electronic Raman transitions to excited state components of the ground state have been observed, though these rue a factor of 50-100 times weaker than the luminescence band origin at 20029 cm(-1). The energies of the observed electronic Raman transitions were found to correlate with sharp vibronic components of the (2)A "(T-2(2g)(H))-->T-4(1g)(F) transition, which confirmed the ground state spinor component energies to be 262, 500, 902, 1052, and 1118 cm(-1). Finally, the quenching of background emission intensity is indicated by the appearance of "holes" in the observed spectra which are due to absorption into various electronic states of the cobalt(II) ion. This emphasises the importance of crystal quality, the presence of other impurities, and even the role of the host material in determining the optical properties of crystals.
