FCS is a National Conference organized every year bringing together scientists and students from multiple disciplines to discuss the new applications and technological developments in the field of optical spectroscopy for solving problems in biology and chemistry. The history of FCS dates back to 2009 when first workshop was first held in TIFR, Mumbai, India. Since then, it has given birth to Fluorescence Society of India involving members from different institutes from all over India and abroad. FCS was first started with an objective to impart working knowledge in Fluorescence Correlation Spectroscopy but over the years it has taken over related field like time-resolved fluorescence, fluorescence microscopy and so on. In 2013, Raman Spectroscopy was also included, terming the conference as FluoRa-2014. This year FCS meeting shall be held in the enchanting and picturesque campus of Indian Institute of Technology Guwahati at Guwahati, Assam which is part of North-East India during December 17 – 21, 2017.
