As the world is demanding more alternative energy sources, Sustainable Development Goal 7 (SDG 7) aims to ensure access to affordable, reliable and sustainable energy for all countries especially least-developed and developing ones. It is important to expand the infrastructure and upgrade technology for supplying these sustainable energy services and fluorescence chemistry plays a huge role on creating this infrastructure.

In this interview, Series Editor of Springer Series in Fluorescence Bruno Pedras shares his insights on how research work done on fluorescence can help achieve this goal and discusses the most recently published book in the series "Fluorescence in Industry".

How can the research in your field help in the context of the grand societal challenges?

Research in the field of fluorescence has always been connected to major societal challenges, and areas such environmental monitoring or medical diagnostics have been the focus of many researchers over the years. In my particular fields of research, and as a PhD holder in Sustainable Chemistry, the pursuit of sustainable development is an ever-present concern. For instance, the development of fluorescence-based probes for metal ion detection finds application in fiber-optic chemical sensors for in-situ monitoring of heavy-metals in waters (SDG 6 and 14); oxygen and temperature nanosensors for intracellular mapping aim at monitoring abnormal oxygen consumption and temperature variations in tumorous cells (since their metabolic activity is altered), contributing to the development of novel diagnoses and therapies and providing solutions to healthcare-related societal challenges (SDG 3); TADF materials for OLED and sensing applications (SDG 7) and luminescence-based sensors for aeronautical applications (SDG 7 and 9) are also examples of how the research in this field may contribute to address some of the great societal challenges.

Why is "Fluorescence in Industry" is an important book?

To the best of my knowledge, this is the first book that addresses fluorescence from an industrial point of view. It is aimed at filling a gap in the literature devoted to fluorescence, by providing different examples of its industrial applications, described by both industry-based researchers and academics who hold strong collaborations with industrial partners. Hence, this volume serves a wide variety of readers coming from both university laboratories (no matter how small or economically constrained) and companies with substantial funding for R&D activities. The former might have incomplete acquaintance with industrial applications and processes, despite their large experience in fundamental research; likewise, the latter may want to expand or update their knowledge on fluorescence science. In both cases, this book is intended to serve as a reference work and to stimulate an interplay of expertise.

In which ways do you think your book is addressing SDG7?

As I see it, this book addresses even more than one SDG. Chapters such as Photoluminescent Glasses and Their Applications, Luminescence in Photovoltaics and Thermally Activated Delayed Fluorescence Emitters for Light-Emitting Diodes and Sensing Applications address SDG7 by focusing on sustainable and energy-efficient materials and devices, which are also ultimately connected to SDG13, stimulating the focus on climate change. SDG6 (related to the need for clean water and its sustainable management) is addressed by the chapter Applications of Submersible Fluorescence Sensors for Monitoring Hydrocarbons in Treated and Untreated Waters. The chapter Instrumentation for Fluorescence Lifetime Measurement Using Photon Counting is related to SDG9 (Industry, Innovation and Infrastructure); while for instance chapters like Fluorescence in Pharmaceutics and Cosmetics or Application of Fluorescence in Life Sciences for Basic Research and Medical Diagnostics relate to SDG3 (Good Health and Well-Being).

What progress would you like to see in your field next towards addressing SDG7?

Concerning SDG 7 specifically, great progress has been made in the design of new functional materials, such as charge-transfer materials that can be applied as electroactive components for energy devices, improving the efficiency of already existing nanostructured light emitters and absorbers, such as light-emitting diodes and solar cells. The challenges of continuously improving the energy efficiency of these materials, combined with a proper and effective translation to the market, while looking for environmentally friendly processing conditions might pave an interesting road ahead in this research field towards addressing SDG 7. 

What advice do you have for researchers who are looking for ways to make societal impact, in other words, impact beyond their scholarly circle/academia?

I would give the same advice that I give myself, even nowadays (not only valid for the field of fluorescence): look for what might be the added value of your fundamental research that can translate into an important practical application, for the benefit of the society as a whole, or your own as individual. This awareness is not always easy to achieve and, most of the times, even when achieved it is not put into practice either by insufficient funding or lack of suitable partners. Therefore, seek the adequate industrial collaboration and establish partnerships that epitomize your ideas into our everyday lives.
