Abstract

The decay behavior of CaAlSiN3:Eu2+ was monitored as a function of the detection wavelength on the Eu2+ emission band for various Eu2+ concentrations from 0.0005 to 0.05. The decay at the higher-energy side was faster and less linear than the lower-energy side decay for all Eu2+ concentrations. This was due to an inhomogeneous broadening induced by the random distribution of Al and Si ions at a crystallographic site in the CaAlSiN3 structure and to the successive site-to-site energy transfer. This phenomenon caused a redshift of the Eu2+ emission band as the Eu2+ concentration increased.

Emission spectra of CaAlSiN 3 : Eu x 2 + ( x = 0.0005 0.05 ) ; the first row shows the emission color, the second row shows the TRPL, and the third row shows the CW emission spectra. Different colors corresponding to each curve in the TRPL stand for different delay times, i.e., black curve is acquired at a delay time of 40 ns, red at 80 ns, green at 120 ns, blue at 160 ns, and so on. (In the print version, the delay time increases from top to bottom.)
