WebThe term upconversion is also sometimes used for other types of processes which generate shorter-wavelength photons.An example is the upconversion of infrared photons to the visible spectral range by sum frequency generation in a nonlinear crystal.This can be used e.g. for photon counting at long wavelengths, where no suitable detectors are available. . …
For photons with high photon energy (MeV scale and higher), pair production is the dominant mode of photon interaction with matter. These interactions were first observed in Patrick Blackett's counter-controlled cloud chamber, leading to the 1948 Nobel Prize in Physics. If the photon is near an atomic nucleus, the energy of a photon can be converted into an electron–positron pair: dewayne chin fortressWebDecember 2024 at Photon Energy Group.

I complete Gerard's answer: up-conversion is the reverse process, where two low frequency photons are converted to a single high-frequency photon. So basically down- and up-conversion correspond to a frequency conversion of the photons through a nonlinear interaction.
