Welcome to PRE'22

As concerns still exist about the spread of the corona virus globally, we well understand that this situation is worrying everyone and that many colleagues are scared to travel. We, as PRE’22 organizers, are deeply concerned with the health and well-being of the participants.
On the other hand, one of the strengths of PRE Workshops has always been the direct interaction of attendees; thus, after shifting PRE’21 to 2022, we are now attempting to find a solution that could leave open the possibility to participate in-person for as many colleagues as possible.

Trying to reduce the need of long distance (transcontinental) flights for prospective participants, we have considered the feasibility of splitting PRE’22 into two events, one in Cancun, Mexico, as already planned for the canceled PRE’21, and one in Europe. Our Asian colleagues could then decide what location would be more convenient for them.

As a first move into this direction, we gladly agreed with the Materials Research Society, USA, and the Sociedad Mexicana de Materiales (SMMater) to organize a Symposium in the frame of the XXX International Materials Research Congress (IMRC), which will be held in Cancun, Mexico, in the week 15 to 19 August.

Our Symposium (C6), entitled Photoluminescence in rare earth doped materials (PRE’22-Mexico), will likely be held on 17-18 August 2022.
For any further detail you are kindly referred to the web page of IMRC-2022.

The second event in 2022, namely the European one, will be in Poland, in September, organized in conjunction with ICMS 2022, the biennial International Conference on Molecular Spectroscopy.
The Symposium on <Photoluminescence in Rare Earths: Photonic Materials> (PRE’22-Poland) will be held during ICMS 2022 on 11-15 September 2022 in Szczawnica (100 km from Krakow).
For any further detail you are kindly referred to the web page of ICMS 2022.

The General Assembly of the United Nations has declared 2022 the International Year of Glass (IYoG). Thus, PRE’22 will also be one of the scientific events to celebrate IYoG !

PRE’22 is the ninth event in the series of International Workshops covering a wide range of research topics concerning the properties and applications of rare-earth ions in optoelectronics and photonics. The series begun in Trento, Italy in May 2005 (PRE’05), followed by PRE’07 again in Trento, PRE’10 in Firenze (Italy), PRE’12 in Kyoto (Japan), PRE’14 in San Sebastián (Spain), PRE’16 in Greenville (USA), PRE’17 in Rome (Italy), and PRE’19 in Nice (France). You can look at more details in the History page.

Almost 1,000 scientists and students from more than 30 countries, in total, have attended the previous Workshops. The average size of each event, around 100 people, makes for a collegial environment where students and world experts can mingle and talk in an informal and effective way.

Over the past decade, an increasing number of luminescent materials have been reported, based on the properties of rare earth ions embedded in different matrices (crystalline, amorphous and glass ceramics; oxides, fluorides, chalcogenides, organics, ….) or contained in molecular complexes. These materials have already been been widely employed in light sources and amplifiers, optical displays, fluorescent probes, luminescent labels, frequency converters, detectors, and so on, thus covering fields ranging from telecommunication to sensing, from medical diagnosis to energy. Despite of it, there are still increasing demands for novel functions to further extend their practical applications.

The PRE’22 Workshops, like the previous ones and despite the difficulties due to Covid-19 pandemic, aim at providing to material scientists, chemists and physicists the opportunity of debating about the state of the art and the perspectives of the photonic materials based on rare earth ions. Both fundamental photoluminescence properties and application oriented material investigations will be considered.
