Webb15 feb. 2024 · Cooling the atoms slows them to a near standstill. Through this cloud of immobilized atoms, the researchers then shine a very weak laser beam — so weak, in fact, that only a handful of photons travel through the cloud at any one time. The researchers then measure the photons as they come out the other side of the atom cloud. WebbThis study demonstrates that photocatalytic performance of TiO 2 –NAA-DBRs is enhanced by the “slow photon” effect when the edges of the PC’s photonic stopband (PSB) fall within the absorbance band of the organic molecules.
