| XIX International Feofilov Symposium on Spectroscopy of Crystals Doped with Rare Earth and Transition Metal Ions (IFS 2025) November 10-14, 2025 Saransk, Russia |
Dear Colleagues,
We invite you to take part in the XIX International Feofilov Symposium on Spectroscopy of Crystals Doped with Rare Earth and Transition Metal Ions (IFS 2025)
The XIX International Feofilov Symposium (IFS 2025) continues a sequence of symposia started in 1965. The first nine events were held as national meetings. For more than 20 years, symposia have been gathering researchers working in the fields of optical spectroscopy and condensed matter physics from all over the world. Recently, IFS are held every 3 years (Kazan – 2001, Ekaterinburg – 2004, Lake Baikal – 2007, St. Petersburg – 2010, Kazan – 2013, St. Petersburg – 2015, Ekaterinburg – 2018, Moscow – 2022).
