Abstract
Sodium β"-alumina (SBA) single crystal is a well-known that fast ionic conductor which has attracted much attention in recent years.1 One application for SEA is to be used as a host crystal for trivaient lanthanide ions such as Nd3+ The structure of SBA consists of spinel - type blocks alternated by loosely packed thin slabs, often referred as conduction planes, where the Nd3+-ions reside. The Nd3+ doped SBA (Nc:SBA) has shown some interesting features as a new solid-state laser gain medium2,3 that has prompted several studies on its structure1 and spectroscopic5,6 properties. In this paper, we report a study on the temperature-dependent fluorescence decay properties for the 4F3/2 level of Nd3+ in SBA crystals.
