Abstract
At high concentrations (approximately 2%) of chromium, the luminescence from ruby is seen to consist of sharp line emission from single ions (S), sharp line emission from ion pairs (P), and broadband emission at longer wavelength from clusters of ions (C). The cluster emission dominates the intensity. Large variations in the intensity and lifetime of the sharp line emissions are observed when the temperature is varied [X.X. Zhang, P. Hong, B. Di Bartolo and C.W. Struck, J. Lumin. 48 49 (1991) 248]. We show that these variations can be accounted for on the basis of a model in which there is efficient energy transfer between single ions and ion pairs and between single ions and clusters.
