摘要：

A new versatile pulsed light-emitting-diode system capable of producing time-resolved luminescence spectra is described. The light-emitting diodes are pulsed by signals from a multivibrator with pulse widths ranging from 25 ns (FWHM) to 30 mu s. Time-resolved luminescence spectra from feldspars and quartz, materials relevant to luminescence dating, have been recorded. Examples of time-resolved spectra and the lifetimes deduced from them are given.
