The final IFS`XVI Program!

Welcome to IFS'XVI!

The Organizing Committee would like to invite scientists to participate in  the XVI International Feofilov Symposium (IFS'XVI) on spectroscopy of crystals doped with rare earth and transition metal ions which is to be held in Saint-Petersburg (Russia), from 9th to 13th November 2015, and is organized by the Saint-Petersburg National Research University of Information Technologies, Mechanics and Optics (ITMO University).


The United Nations General Assembly has proclaimed 2015 as the International Year of Light and Light-based Technologies (IYL 2015). Backed by UNESCO, IYL 2015 is a global, cross-educational  initiative aiming to raise awareness of the role placed by light and light-based technologies throughout modern society, and potential future developments and applications. Over 80 countries around the world have shown their support for the initiative.

We are looking forward to seeing you in Saint-Petersburg!

Organizing Committee IFS'XVI


The XVI-th Feofilov symposium continues a sequence of symposia started in 1965. The first nine symposia were held as national meetings. The X-th (St. Petersburg, 1995), XI-th (Kazan, 2001), XII-th (Ekaterinburg, 2004), XIII-th (Lake Baikal, 2007), XIV-th (St. Petersburg, 2010) and XV-th (Kazan, 2013) symposia were held with international participation.



The XVI International Feofilov Symposium is dedicated to P. Feofilov`s 100th anniversary.

Petr P. Feofilovcorresponding member of the USSR Academy of Sciences, is one of the most famous Russian scientists. He began his research under the supervision of member  S.I. Vavilov, Academician of the USSR Academy of Sciences.

P. Feofilov has made a great contribution to the development of physics of crystals doped with transition metal ions. He is one of the first in the world to have begun the systematic investigation of the optical properties of crystals comprising ions with uncompleted shell, e.g. rare earth (RE) ions and uranium. He was the first to state such essential problems as multiple activator sites problem, crystal-chemical conditions of activation, physical structure and energy of the RE-sites.
