title: Towards models for analysis of time-resolved luminescence spectra from quartz.
abstract: Simple and stretched-exponential models for use in the analysis of time-resolved luminescence spectra from quartz are compared. The methods have been applied to evaluate lifetimes from portions of time-resolved luminescence spectra measured either during or after the luminescence stimulating pulse. We discuss the basis for use of the exponential functions as well as examine the application of, in this context, atypical stretched-exponential functions for analysis of time-resolved luminescence spectra from quartz.
