Observation of Single-and Two-Photon Luminescence on Optically Quenched Wide-gap Semiconductor Crystals
Simultaneous observation of quenched wide-gap semiconductor crystals has been observed using single-and two-photon luminescence. It is was found at the quenched area, single-photon excitation gives luminescence read-out compared to two-photon which no luminescence detected at the bandgap wavelength. This is due to transition of electron between the bandgap in the two-photon luminescence to occur have been demolished by the quenching which involved two-photon quenching process. Furthermore, side lobes that exist in the longer part of the luminescence spectrum are resulted by decreasing in the Stark effect which increased the transition energy. The dependency if excitation power with the observed from the crystals luminescence is elaborated which confirmed the single-and two-photon luminescence methods.
