1. Method to deposit 2 - 5 component Te-based alloy byy  evaporation from one source  was developed.
Methods to deposit PE, PVDF, PTFE, PPS by vacuum evaporation were developed.  Polyparaxylylene films were deposited by both pyrolysis and plasma methods.
Many kinds of dyes were tested to evaporate.  Dye films with big absorption in UV-VIS and NIR  were obtained. Phthalocyanine, merocyanine, squarylium (download pdf), metal complexes, other polymethine dyes were used. Methods to improve film stability, to prevent aggregation and crystallisation were developed.
Unusual effects were found using  Laser evaporation of dyes. It is new route to control film structure and optical properties.
Co-deposition of polymers with dyes is studied. Polymer films filled by metal and dye nano-particles have been deposited. Compatible pairs which form film acceptable for optical recording were found. Dye nano-composites reveal interesting features in optical properties.
Deposition process was monitored by the optical system of both film reflectance and transmittance  measurements in situ. Quartz crystal microbalances also were used.

2. Oriented growth of Squarylium derivatives onto aligned by friction transfer and vacuum evaporation with rubbing PTFE and PPS films was studied. Orientation strongly dependent on dye end and side groups.
3.The influence of end and side dye groups on the film optical properties are studied. New dyes including asymmetrical ones were tested. Deposition technique allows to control dye film structure and film properties as well. Uderstanding how to control organic film optical properties promoting or supressing aggregation by both dye chemical structure modification and deposition technology was acquired.

4. Discharge was excited  at 40,68 MHz, 5,0 MHz, by 2 kV at 50 Hz and pulsed voltage.
Te(C3H5)2, Se(C3H5)2, Sn(C3H5)4, Sb(C3H5)3, bis-allylPdCl were used. Dependent on pressure, flow rate, voltage, current density, frequency and substrate temperature both high-polymeric and metallic films were produced.
Plasma polymerisation of  complex molecules with functional groups was tried. Films with not damaged functional groups were obtained by matching molecule chemical structure with plasma parameters.
 Combined deposition methods  are developing. They include  molecule transmission to gas phase by thermal or laser evaporation and farther treatment by mild plasma or electron beam action to activate selective chemical bond. Film growth includes chemical reactions. By this way thin organic film with complex molecular structure can be deposited.

5. Glass tubes of 14 mm diameter were used. Methods to deposit polymer, dye, metal, Te-based alloy, metal-polymer film with properties needed for optical media by PECVD and vacuum evaporation were developed.
6. Marks were recorded at 180 c-1 (30 rps) by Nd:YAG laser (532) nm and by semiconductor laser (830 nm). Spot diameter was 0,8 -1,2 mcm (1/e2), power was 5-50 mW, pulse duration was  75-150  ns.
6.1. Functions of viscosity and volume of gaseous decomposition products vs temperature  of polymer matrix determine writing threshold and shape of recorded marks in metal-polymer media.
6.2.Metal concentration, its thermal conductivity and melting temperature determine mechanism of morphological changes in irradiated domain and recording energy.
6.3.Recording energy and mechanism of morphological changes are dependent not only on metal concentration, but also on metal particles distribution in polymer matrix and correlate with electrical resistance. 
6.4.Three types: flow, ablation and evaporation marks with different hole rim shape were prepared in dye thin film media. The understanding, how to produce each type of hole was gained.

Nonlinear optical properties of ansymmetric dye solid films have been studied.

7. Using combined co-deposition methods, molecular nano-composite films are deposited.
To receive properties wanted all chain to be included into design:
- chemical structure design, than compoundd synthesis,
- deposition conditions: evaporation, gas phase manipulation, substrate treatment,
 - post-deposition treatment.
Using this approach, several dye-filled polymer systems were deposited. At first dielectric polymers were used as matris. Dye-filled polymer films optical spectra exhibit transformation from monomer to dimer state in agreement with dye concntration. Such systems are  extremely stable: some deposited in 1988 and in 1994 are still unchanged.
 Purposefully  modifying dye structure and choosing appropriate polymer, it is possible to control intermolecular interactions, therefore nanoparticle size, electron levels, and consequent properties. Deposition contitions effect structure, orientation and organisation strongly.

8. STCU Project 2348:
Construction of Organic Dye Films for Nonlinear Applications by Gas Phase Deposition.

Farther progress in the field of the gas phase deposition of organic films for optical devices will be the result of the joint efforts of the chemists, physicists and  technologists together: our team will design the dye-filled polymer films for nonlinear optics. The design steps as follow:

 1.Computer simulation of compounds with high hyperpolarizability.
 2.Chemical synthesis of calculated compounds.
 3. Mastering the ways to control the phase state, composition, crystallinity and molecular orientation of  material in the solid  film. Both the chemical modification of compounds and deposition conditions to be used.
 4. Development of methods and equipment for deposition of multi-component films with a given composition.  By controlling the rate of inter- and intramolecular interactions in forming material, composite or solid solution or joining the chromophore  to polymer chain can be obtained.
