Welcome

We cordially invite you to attend ICL 2026, which will be organized at Kyoto University, Kyoto, Japan on Sept 22 - 26, 2026.

The ICL conference has an old history of 60-years since 1966 and has been well organized every three years in different countries of the world: Budapest (Hungary, 1966), Delaware (USA, 1968), Saint Petersburg (Russia, 1972), Tokyo (Japan, 1975), Paris (France, 1978), Berlin (Germany, 1981), Madison (USA, 1984), Beijing (China, 1987), Lisbon (Portugal, 1990), Storrs (USA, 1993), Prague (Czech Republic, 1996), Osaka (Japan, 1999), Budapest (Hungary, 2002),  Beijing (China, 2005), Lyon (France, 2008), Ann Arbor (USA, 2011) and Wroclaw (Poland, 2014), Joao Pessoa (Brazil, 2017) , Changchun (China 2021), and Paris (France, 2023)

We are honored to hold it again in Japan after 27 years.

ICL is an international conference series held with a program focused on all types of luminescent materials, the processes governing light emission and the applications of these systems.

The 21st Conference in 2026 is organized at the Yoshida-South campus, the south-side of the main campus of Kyoto University.

ICOOPMA2026 will be held just before ICL in Hamamatsu city.
Kyoto is just 66 min west by Shinkansen(Hikari) from Hamamatsu city, which runs every hour.

Focus

The conference will feature a scientific program focused on:

  • New luminescent materials and new methods
  • Nanocrystals, quantum dots, nano-structured, and 2D materials
  • Spectroscopy of inorganic phosphors, semiconductors, and molecular systems
  • Luminescent materials for imaging, bio-imaging, and theranostics
  • Persistent luminescence and photo-stimulated luminescence
  • Excited state dynamics and ultrafast processes
  • Coherent, nonlinear, and high-resolution spectroscopy, quantum emitters, quantum technologies
  • Theoretical modelling and computational methods for luminescence phenomena
  • Field-induced luminescence in organic and inorganic media, OLEDs, and FEDs
  • Dynamics of photovoltaic and photocatalysis materials
  • Luminescence materials for energy and environmental sciences.
