Can photons combine
WebApr 11, 2024 · To improve the quantum efficiency and luminous intensity of PL, it is necessary to combine luminescent materials with optical structures. Upconversion nanoparticles (UCNPs), which can convert near-infrared light to visible light, become possible through two-photon or multi-photon processes. ... In the EL process, photons … WebNov 26, 2009 · The resulting particles have a high kinetic energy and can then heat water that drives a heat engine. You could in principle store electrons and anti-electrons in two different containers, let them combine and form two photons with high kinetic energy that you then harvest. The basic reason why this is not done that it's just not practical.

WebThe electron can absorb photons that will make it's charge positive, but it will no longer be bound the the atom, and won't be a part of it. For example at -10ev, it can absorb, 4eV (will move to -6eV), 6eV (will move to -4eV), 7eV (will move to -3eV), and anything above 7eV (will leave the atom) If either the electron or positron, or both, have appreciable kinetic energies, other heavier particles can also be produced (such as D mesons or B mesons), since there is enough kinetic energy in the relative velocities to provide the rest energies of those particles. Alternatively, it is possible to produce photons and other light particles, but they will emerge with higher kinetic energies.
WebFeb 16, 2024 · Polaritons have mass, which is how they can bind to other polaritons. Once they leave the cloud, the atoms they've picked up stay behind, but the photons remain bound together. Since these...
