Abstract
This paper reports on the time-resolved emission spectra and the fluorescence decays of Nd3+ in ASN (Srl-xNdyLax-yMgxAl12-xO19 with [MATH] and [MATH]). The Nd3+ decay profiles are fitted according to the Hopping model. The decay time decreases with increasing y due to strong interactions between Nd3+ ions. Fluorescence intensity is given as a function of x and y and is maximum for y values close to 0.1.
