The details of the luminescence spectra and the decay characteristics of theluminescence have been examined over a wide range of temperature. At lowtemperatures, the luminescence decay curve after the fl-band excitation has twocomponents, fast and slow. The difference between the decay times, about 10 nsand 4.1 ms at 4.2 K, enables one to decompose the emission spectrum into the'T..+"A.. and 'A..+"A.. bands by time-resolved emission spectroscopy. Thezero-phonon line at 445.3 nm of the former band and the zero-phonon line (,4(,)at 460.7 nm and the one-phonon line at 465.0 nm of the latter band are observedat 6 K. The A,) line grows under an external magnetic field. The optical excitationmechanism has been also examined by observing the excitation spectra at varioustemperatures.
