Luminescent Radicals

Chemical Reviews
Organic radicals are attracting increasing interest as a new class of molecular emitters. They demonstrate electronic excitation and relaxation dynamics based on their doublet or higher multiplet spin states, which are different from those based on singlet-triplet manifolds of conventional closed-shell molecules.

Visual Luminescence and Luminescence Imaging

2013
Visual luminescence excited by UV light and luminescence imaging are discussed as simple and effective techniques for preliminary characterization of diamonds and as methods of recognition of HPHT-treated diamonds. Since all natural diamonds fluoresce under UV excitation, the visual luminescence technique is a common method applicable to diamonds of ...
