✦ Synopsis

The results of the absorption, infrared, Raman and fluorescence spectra are reported. Owing the analysis of vibrational levels based upon the IR and Raman spectra the assignment of vibronic peaks of throrescence spectra is proposed. The anomalous concentration dependence of fluorescence decay rates is found. A discussion of the possible mechanism responsible for concentration quenching of Nd3+ fluorescence in the CszNa(La,Nd)C16 crystal indicates that at low temperature the non-resonant cross relaxation occurs whereas at room temperature both the non-resonant cross relaxation and the anti-Stokes resonant cross relaxation contribute in the Process.
