Light-emission intensity of CdS nanoparticles doped in a PMMA film is enhanced by a UV irradiation in air, but the emission intensity is strongly de-enhanced at a low pressure of 10-5 torr. Atmospheric gas as well as UV irradiation is essential for the enhancement, and these enhancement and de-enhancement processes are almost completely reversible. The emission of CdS nanoparticles doped in a PMMA film is also quenched by applying an external electric field, suggesting that the non-radiative decay rate from the emissive exciton state is accelerated by an external electric field.
