About Petr P. Feofilov

He was one of the first in the world to begin a systematic investigation of the optical properties of crystals containing ions with incomplete f shell, e.g. RE and uranium ions. He was the first to state such essential problems as multiple activator sites, crystal-chemical conditions of activation, physical structure and energy levels of the RE sites. P.P. Feofilov has developed and successfully implemented the method of polarized luminescence for investigation of the RE sites. The book “Polarized luminescence of molecules, solutions and crystals” is now a classical course book to study luminescence spectroscopy. The studies of luminescence properties of crystals performed by Petr Feofilov made it possible to create a laser based on calcium fluoride doped with samarium and uranium ions – one of the first solid-state lasers. P.P. Feofilov’s research had a great impact on such areas of solid state physics as crystallography and optical spectroscopy of defects in crystals. It should also be noted that Feofilov was a friendly, open-minded and multi-talented person.

In memory of Acad. Alexander A. Kaplyansky, former honor IFS chairman.

Prof. Alexander A. Kaplyansky is a world-wide recognized scientist in the field of optical spectroscopy of solid state.
In 1953 he has graduated from physical faculty of the Leningrad State University (now Sankt-Petersburg State University). In 1957 as a Ph.D.
student under supervising of the Acad. Prof. Eugeny Gross he defended at the Leningrad physical-technical institute (now A.F. Ioffe Physicaltechnical
Institute of the Russian Academy of Sciences (RAS)) the theses on the problem of detecting and studying the line structure of the
fundamental absorption edge of semiconductors associated with the optical excitation of excitons. In 1967 he has defended second doctor degree
on the topic of “Piezospectroscopy of crystals.”
For a long time he headed the laboratory of solid state spectroscopy of the A. F. Ioffe Physico-Technical Institute RAS. In 1987 he was elected
corresponding member of the USSR Academy of Sciences, and in 2003 was elected as academician of the Russian Academy of Sciences.
He discovered and studied a lot of phenomena: the optical anisotropy of cubic crystals in the exciton resonance region; the splitting of exciton
transition lines under the action of uniaxial elastic compression of crystals; the exciton structure in the photoconductivity spectra of semiconductors;
the reversible splitting of spectral lines of impurity spectra in crystals under the action of directed elastic deformation; the structural
phase ferroelastic transition in a new class of dielectric crystals (mercury halides) with unique anisotropic properties; the spontaneous formation
of stable domains in impurity dielectrics (concentrated ruby) under the influence of strong optical excitation. Also, he found out the role of
inverse local symmetry of impurity centers in the phenomenon of burning holes in the spectra of impurities.
In the series of works Kaplyansky A.A. and his colleagues studied by optical methods terahertz nonequilibrium phonons in crystalline and noncrystalline
dielectrics and semiconductors, in systems with quantum wells, ceramics, fibers: modes of their propagation, scattering by defects,
interaction with electronic levels of impurities and excitons, etc.
