Characterisation of New Layered Cr(III) Doped in Chlorocadmium Phosphate Cd(HPO_4)Cl.H_3N(CH_2)_6NH_3_(0.5) Crystal by EPR and Optical Studies

摘要

Open-framework crystalline solids containing micro or mesoporosity have a great potential in material science. They are searched not only for their catalytic properties or their use as molecular sieves, but also they are exploited for other areas that include electronic materials, photochemical and photophysical processes. Several investigators have prepared and reported heteropolyphosphate anions built from ZnO_4 and PO_4 tetrahedra and an organic cation.
