was taken for investigation. Water molecules are able to create molecular associates using Van der Waals forces as well as labile hydrogen interactions [ -]. Owing to hydrogen bonds molecules of water are capable to form not only random associates one having no ordered structure but clusters, i.e. associates having some ordered structure [ -]. The network of hydrogen bonds and the high order of intermolecular cooperativity facilitate long-range propagation of molecular excitations [ , ]. This allows, in principle, to consider water and water-based solutions as systems sensitive to weak external forces. Indeed, the study of luminescence at long time scale shows that the structural equilibrium in water is not stable it changes after dissolution of small portions of added substances and after exposition of aqueous samples to UV and mild X-ray irradiation [ ].

The development of new methods to improve physical and stressstrain properties of materials is an important contribution to the development of modern technologies and targeted control of their behavior. The optimum combination of stressstrain properties and electrical ones to improve performance attributes of materials is very important. The basic purpose of this work is the study of long-term effects in materials resistivity changes after treatment in a glow discharge. There are presented the results of measurements of a resistivity relative value in copper-graphite insertions after a radiation treatment in a glow discharge. The graphic dependences obtained show that in the course of two years in samples a long-lived state, a structure of irradiated composite material remains. It is a sign of that the improvement of performance attributes of insertions investigated bears longterm character. An anomalous temperature dependence of electric resistance after an irradiation treatment if a glow discharge was detected in technical copper samples. First of all this anomaly manifests itself in copper resis-tivity decrease after an irradiation treatment at different temperatures obtained that is contrary to the fact determined of the simultaneous increase of dislocations density in samples irradiated.

Investigations of the photoluminescence spectra of zinc oxide microrods grown from a vapor phase were performed. It was concluded that the green photoluminescence of ZnO can be related to the electronic transitions from Zn + i donor levels on the V Zn neutral acceptor levels and emission from the singly ionized oxygen vacancy V + O levels, respectively.
