Abstract:
1. A photomultiplier tube comprising: a photocathode; a first electrode; a second electrode opposedly disposed to the first electrode and separated from the first electrode to create a space therebetween; an anode opposedly disposed to the photocathode, the first electrode and the second electrode being disposed between the anode and the photocathode, the photocathode being adjacent to the first electrode and separated from it, and the anode being adjacent to the second electrode and separated from it; and an amplifying medium disposed in the space between the first electrode and the second electrode, wherein the amplifying medium comprises both metal oxide nanoparticles and an aerogel, the metal oxide nanoparticles have an aspect ratio greater than or equal to 5 and are in the form of agglomerates, and the aerogel comprises one or more of a metal oxide aerogel, a graphene oxide aerogel, a chalcogel, an organic aerogel, and combinations thereof.
