There are materials which absorb photons


There are materials which absorb photons of shorter wavelength and emit photons of longer wavelength. Can there be stable substances which absorb photons of larger wavelength and emit light of shorter wavelength?


The wavelength of the photon increases when the frequency decreases. There are two possible cases and they are; case one in which the photons have a smaller

wavelength and the energy is consumed against work function. In case two, the photons might have a longer wavelength and emit photons with shorter and lesser
