PRE is the acronym indicating the series of International Workshops on Photoluminescence of Rare-Earth: Photonic Materials and Applications, begun in Trento, Italy, in May 2005, on the initiative of Maurizio Ferrari and Giancarlo C. Righini. These Workshops are sponsored by the TC20 Committee (Photonic Glasses and Optical Fibers) of the International Commission on Glass (ICG).

All the Workshops have been quite successful and keep providing excellent opportunities for discussions between researchers working on photoluminescence of rare-earth ions in various materials and devices, as well as on their applications.

Here there are some data about the past PREs (the number of contributions includes all types of presentation, namely invited, oral, and poster). Since 2016, dr. Righini has been appointed Honorary Chair of the PRE Workshops.
