The video shows "a false-colour movie recorded with an EMCCD camera showing the build-up of the quantum interference pattern for PcH2 molecules. Images were recorded before deposition of the molecules." From the paper: "The phthalocyanine molecule PcH2 and its derivative F24PcH2 were selected because they are stable molecules and efficient dyes, even in vacuum. The molecular sample on W2 was illuminated under a shallow angle so that the excitation laser did not enter the imaging optics. Fluorescence was collected by a microscope objective, filtered, and imaged onto the single-photon-sensitive electron-multiplying charge-coupled device (EMCCD) camera."
