Web10 apr. 2024 · Once hit by energetic electrons, ionized nitrogen molecules (N2+) emit photons which wavelengths are in the deep-blue/purple (450-400nm). Since N2+ is ionized there are lower energy electrons being shot out as well, allowing stable gaseous N2 to get excited and emit photons, which wavelengths are in the active red/deep-red (650-680nm). Web8 dec. 2024 · To give you the best chance of early detection, the National Fire Protection Association recommends having both types of sensors in your home.
