-          Investigated the proper and impurity electronic excitations, recombination processes and luminescense in hallogenides of alkylammonium and alkylphosphonium.

С) of products (also radicals) obtained in the result of influence of photoirradiation, radiation, heating and have been studied the converting mechanism and their stages carried out under these influences.

-          the applying of new modern high-sensitive devices received by Institute allowed more thoroughly investigate the organic compounds, oil and oil products by modern physical-chemical methods.

1. Developed the scientific bases of obtaining of crystal phosphors new class on the basis of alkylammonium and alkylphosphonium halogenides, activated with ions Tl⁺, Pb²⁺, Bi³⁺ and are shown that they have wider range of variation of spectral-luminescence characteristic in comparison with AHC and АHC- phosphors.
2. On the bases of complexes of lead haloid salts with primary aliphatic amines are developed a previously unknown class of highly efficient phosphors studied in visible and the near IR region of spectrum and exceeding in the quantum yield of luminescence of many known photo-luminophores.
3. PbBr₂ ·CH₃NH₂ complex and luminophore on its basis are recommended as an effective converter visible narrowband luminescence  (2,33эВ) not only wider range of UV-rays, but also IR-laser rays (on mechanism of two-photon luminescence).
4. Developed the scientific bases of luminophores obtaining on the bases of heavy oil residues and is defined that they are reversible accumulators of solar energy, photosensitizers of organic compounds decomposition with hydrogen obtaining, luminescent colorants for polymers, penetrants for capillary defectoscopy, photochromic materials for reversible photochemical processes.
5. It is defined that oil luminophores unlike synthetics have variables luminescent properties. Showed that from the fractions of heavy oil residues can be obtained luminophores possessing the luminescence color that characteristic for all colors of the rainbow.
6. In the heavy oil residues are defined not only radicals typical for the resinous-asphaltene substances, but also aromatic hydrocarbons (pery-naphthenic radical). It is shown that under the influence of photoirradiation in these systems occurred not only radicals’ generation, but also their destruction. For the first time defined that the photochromic properties of pery-naphthene radicals.
7. It is shown that resinous-asphaltene substances of oil are universal antioxidants of oil luminophores and other organic compounds combining in it all the basic mechanisms of stabilization of UV- screening, quenching of molecules excited states and inhibiting of photochemical reactions. 
8. The luminophore obtained on the basis of heavy gas oil of catalytic cracking is tested and applied in more than 20 enterprises:
9. “Monokrystalreactiv” (Kharkov city), in “Atommash” (Volgodonsk city), “Neftegasavtomat” (Sumgait city) and etc.
