Cd13P4S22I2 ? a new holographic recording material

Ethyldimethylphenylammonium-halogenoantimonate(III)

“…Gruppe des Periodensystems mit Organylammoniumhalogeniden fu È hren zu Salzen, in deren Strukturen monomere oder oligomere Halogenoanionen in eine Matrix organischer Kationen eingebettet sind. In dieser Hinsicht sind sie in ihrem Aufbauprinzip Argyroditen [1] und Silleniten [2] a È hnlich, die Verbindungsklassen mit groûen elektro-optischen Effekten sind. In den Strukturen dieser Verbindungen finden sich ebenfalls ¹monomereª Anionen in einer, allerdings anorganischen Matrix.…”

Photorefractive effect in doped Pb5Ge3O11 and in (Pb1−xBax)5Ge3O11

“…1 The research on photorefractive materials has been concentrated both on crystals exhibiting very large effects 2 and on so-called nonideal materials. 3 Improving or tailoring the properties of known materials as well as the search for new photorefractive crystals have gained much attention in recent years.…”
