The Matrix

AbstractIn this paper the relationships between the crystal structure, chemical composition and electronic structure of laser materials, and their optical properties are discussed. A brief description is given of the different laser activators and of the influence of the matrix on laser characteristics in terms of crystal field strength, symmetry, covalency and phonon frequencies. The last part of the paper lays emphasis on the means to optimize the matrix-activator properties such as control of the oxidation state and site occupancy of the activator and influence of its concentration.

Fluorine Determination

It has recently been shown by W. Nieuwenkamp that matlockite is identical in chemical composition and crystal-structure with artificial lead fluochloride PbFC1. His conclusion is based upon powder photographs of the two substances and a fluorine determination of a specimen of matlockite from Matlock, Derbyshire. The present work was undertaken primarily to check Nieuwenkamp's interesting results. Access to an exceptionally fine suite of matlockite specimens in the British Museum collection made possible single crystal X-ray measurements, accurate optical determinations, and a new chemical analysis.

The article describes the main features of a new class of colloidal nanoparticles with the electronic structure of semiconductor quantum wells – atomically-thin cadmium selinide CdSe and cadmium telluride CdTe nanosheets with a thickness of 1-2 nm and extended lateral sizes in the range of 100–700 nm. Approaches to the synthesis of such nanostructures by wet chemical methods are considered. A new effect of spontaneous folding induced by ligand exchange has been described.
