Abstract
For Ca 3 (PO 4 ) 2 :Cu phosphor, measurements of spectral distributions of luminescence, reflectivity and quantum efficiency, temperature dependence of luminescence intensity and decay constants are carried out. The one-dimensional configurational coordinate curves for the luminescence center in this phosphor are determined by analysing spectral data. Some characteristics expected from these curves are compared with the observed; the agreement in the absorption band width and the disagreement in the activation energy for nonradiative transition are obtained. The relations between one- and many-dimensional models are investigated and the cause for the above disagreement is attributed to the simplicity of the assumed model. Discussions are also made on the nonradiative transitions in this center.
