Abstract

An optical material encountered during ongoing field collection activities displays tenebrescence, fluorescence and photo-refractive properties. The material is an uncommon variety of sodalite called hackmanite. It is part of the tectosilicate family, a type of silca-based polymer structure, which was discovered to accommodate two separate dopant sites within close proximity to each for fast carrier mobility. The dopants serve to either create vacancies or donors of electrons within the material, thus providing the carriers to be manipulated. Variations of these materials can be found in either an isometric (hackmanite) or asymmetric (marialite) forms providing for application in the development of nonlinear optical devices, i.e. frequency mixers or harmonic sum or difference generation. Also discovered were results that indicated a lack of sulphur being present, contrary to previous publications.
