Summary
Energy is one of most critical challenges that society is facing and reducing energy consumption and CO2 emissions is becoming an increasingly important task in order to achieve a sustainable society. Probably the most important sector where energy consumption can be reduced is lighting. Consequently, it is important and timely to develop energy efficient lighting technology beyond the state of art. An important task in evaluation of new materials for the next generation of light sources is their photophysical characterization. In this the research-grade spectrofluorimeter will be key equipment.
