Investigation of organic liquid phase electroluminescence (traditionally, the
so-called “electro-chemiluminescence” or “electrogenerated chemiluminescence”) is of
special interest as a competitor for “liquid” and “solid” organic light emitted diodes
(OLEDs). From the electrochemical point of view, chemiluminescence is a selfregenerating
process providing high brightness light radiation due to recombination of
oppositely charged dye radicals. Chemiluminescent displays have a competitive set of
parameters: high light efficiency, low power consumption, low driving voltages, fast
response time, high spatial resolution, very high optical transmission and wide operation
temperature range. No polarizers or alignment layers are required. Samples of
chemiluminescent displays, including matrix microdisplays and micromechanically made
cells are available; its design and parameters are discussed in details. Theoretical and
experimental investigations of thin film DC chemiluminescence phenomena are carried
out. On the basis of obtained experimental results, the most important physical processes
have been investigated: charge injection into solution and charge transfer by
electrohydrodynamic flows. Further prospects of chemiluminescent display devices are
discussed.

A new approach to nanoporous silicon formation is proposed. Anomalies both
in low current densities and low fluorine ion concentrations, which is lead to low
uniformity of formed porous silicon, are under consideration. It is shown that at very low
current densities and fluorine ion concentration high uniformity, high porosity
nanoporous silicon layers can be created. Structural, electrical and optical properties of
porous silicon formed in a wide range of current densities, doping levels of silicon
substrates and fluorine concentrations are presented.

Andreev, A.; Andreeva, T.; Kompanets, I.
The process of FLC director reorientation in alternating electric field is
considered for the case when interaction of FLC molecules with the substrates results in
partial unwinding the helix structure and motion of domain walls. The hysteresis-free
electrooptical response as fast as 50…70 μs was achieved in the FLC cell of 1.3-μm
thickness in the electric field 1 V/μm. This result is very important for the practical use of
FLC in fast active matrix displays.

Muravsky, A.; Agabekov, V.; Ariko, N.; Shachab, S.; Tolstik, A.; Malashko, P.
New guest-host dyes of red and purple colour suitable for fabrication of
ultrathin film polarizer from polymerizable liquid crystals are developed. When the
absorption spectrum of dye matches the photopic curve, samples with total film thickness
below 50 μm show good visual contrast.
