L-155 Survey on State-of-the-Art Near-Infrared Emitting Compositions for Flares and Tracers
For clandestine signalling and illumination purposes in the near infrared range (0.7 – 1.0 µm) pyrotechnic compositions based on either potassium and/or cesium compounds are used that are based on the intense emission lines of both K and Cs in the infrared.
