| Abstract: | We have considered the special features of growth for the Nd compounds in the form of monocrystals containing a high concentration of Nd ions (>1021 ions/cm3) with an anamolously low concentration quenching. These compounds are known popularly as “nezoites” containing isolated Nd polyhedra in the structure, which gives a clue to the technology of growth. All the known nezoite crystals, their X-ray analyses and the conditions of growth from multicomponent systems are tested. At present there are two well-known methods of growing nezoites: (1) by evaporation of the solvent at constant temperature and pressure; and (2) by flux method. The authors have discussed the advantages and disadvantages of these two methods. The problem of the presence of light extinguishing admixtures, particularly (OH) molecules in the crystals, and the influence of these admixtures on the basic properties of these crystals (nezoites) is discussed in detail. |
