This XVIIthInternational Krutyn Summer School - "Breaking Through Experimental, Theoretical and Applications of Advanced Luminescent Lanthanide-Based Materials"- is organized by the Institute of Physical Chemistry of the Polish Academy of Sciences, Poland, and Universidade Federal de Pernambuco, Brazil. The School  is conceived as a high-level and highly intensive scientific event focusing on cutting-edge know-how on inorganic and organic aspects of advanced luminescent materials based on lanthanide compounds. The Co-Chairman and Scientific Director is Professor Oscar Loureiro Malta, world-distinguished expert on lanthanide chemistry and physics, and the summer school is also to celebrate his 60th birthday as well as his outstanding contribution to the field  of lanthanide R&D.This Summer School aims at the state-of-the-art training in the form of lectures and consulting sessions designed for Ph.D. students and young researchers seeking to reinforce their knowledge and skills in the field of inorganic and organic aspects of advanced luminescent materials. Top experts in this area will deliver lectures and consulting sessions. The school is intended both for people already active in this R&D field, as well as for those new to the field.  A number of social events will be also proposed to relax after the heavily-scheduled program, including: discotheque, bonfire, boats on Krutynia River, guided, or individual out-door activities (kayaking, trekking, horse-riding, bike, Nordic walking, sailing, high-class ballooning, etc.). The Local Organizing Committee cordially invites you to take part in this Summer School.VENUE The School will be held in a picturesque and romantic summer resort – the village Krutyn – in Masurian Lake District, easily accessible from Warsaw by public buses, but transportation from Warsaw to Krutyn will be provided by the organizers on June 14  (for details see page 2). The Conference Complex “MAZUR-SYRENKA” ensures an excellent conference and accommodation services.
