The sample luminescence was dispersed by either a 3/4 m single monochromator (Spex 1702) or a 0.85 m double monochromator (Spex 1402) and detected by a PMT (RCA C31034). For lifetime measurements the laser beam was chopped by an acoustooptic modulator (Coherent 305, Stanford Research DS 345 function generator), and the signals were recorded with a multichannel scaler (SR 430). Sample cooling was achieved with a He flow technique.
