Inorganic hosts, crystalline

Owing to the relatively good crystallinity and the large number of OOZ reflections observed for the hydro calumite derivative, the electron density distribution along the c axis can be estimated using a series of OOZ reflections, in accordance with previous literature [82,83]. One-dimensional electron density calculations based on X-ray diffraction are often carried out to probe the structure of the intercalated species in two-dimensional inorganic hosts [33,84-86]. This yields specific information about the orientation and structure of the intercalated species or at least ehminates certain conformational possibihties, which are incompatible with the diffraction data. In LDH systems, however, such calciflations are usually impossible because the X-ray diffraction patterns of hybrid materials are often very ill defined [87,88]. 

Intercalation compounds contain a rigid bidimensional crystalline lattice (matrix) which can incorporate molecular or ionic species between the layers to form a peculiar type of host-guest complex [297-299]. Intercalation of metallocenes into various inorganic hosts lattices has been the subject of much attention in recent years [300-304].

The luminescent material may be considered as a transformer of energy, i.e.. from ultraviolet photons to photons of lower energy from cathode rays to photons front electric fields to photons, etc. An inorganic luminescent material, or phosphor, usually consists of a crystalline host materia) to which is added a trace of an impurity (activator and eoactivaturl.
