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. . … WebJan 19, 2024 · The QC stores the photon energy in chemical bonds and releases it as thermal energy (Δ H storage) in a process of converting back to NBD activated by light (hv 2), heat, or catalyst (Fig. 12a and b). The energy stored by photo-isomer can primarily be used for; (1) heating/cooling of houses in winter in temperate regions, and (2) electrical ...
