Magnetic and Optical Properties of Rb and Cs Clusters Incorporated into Zeolite A

Abstract

Optical and magnetic properties are studied on Rb and Cs clusters incorporated into the cages of aluminosilicate zeolite A (structure type code LTA), where α and β cages with inside diameters of∼ 1.1 and∼ 0.7 nm, respectively, are arrayed in a simple cubic structure. The average number of guest alkali atoms per α cage, n, was changed from dilute loading to∼ 5 and∼ 3.5 for Rb and Cs, respectively. At n> 2, the absorption coefficient at mid- infrared region increases significantly. This is assigned to a contribution of the Drude term ...
