Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of the material are excited to a higher energy state.

Novel spectroscopy technique sheds light on nitrogen oxides reductionWhen power plants burn fossil fuels at high temperatures, nitrogen and oxygen molecules break apart and then recombine to form a class of compounds called nitrogen oxides, or NOx. These gases are major pollutants and contribute to—among other things—acid rain and global warming.
