On the Energy Transfer in Bi2WO6: ERedOx Assisted Radiative Recombination in O2 and ROS Sensing. Prospective

Photoluminescence maximum emission signal of colloids based on Bi ₂ WO ₆ suspended in an aqueous solution is blue-shifted as compared to its band gap according to E _{g +} (E _RedOx -E _CB ). This process involves the exergonic non-radiative transfer of E _CB electron to E _RedOx and the concomitant radiative emission of a second electron that has gained E _RedOx -E _CB energy presumably by electrons energy levels entanglement induced via simultaneous light excitement of multiple electrons. These results constitute evidence for energy transfer with application in sensing electrolyte-electron-acceptors as reactive oxygen species that may be implemented for example in cancer and aortic dissection detection and treatment.
