ORIENTED BASIC RESEARCH IN THE PHYSICAL SCIENCES.

Abstract

The optical absorption of both pure alkali halides and alloys of RbCl-RbI, KCl-KI was measured at temperatures low enough to reveal previously unobserved structure in excitonic absorption lines. Studies of intrinsic luminescence have revealed new emission bands probably related to trapped exciton states, and have demonstrated the importance of host sensitized luminescence in the alkali halides. Two photon absorption measurements were attempted in KCl:Ag and NaCl:Ag. The two photon absorption spectrum of ZnS and CdS was measured over a two photon energy range of 2.5eV to 4.2eV.
