Ground and excited state photoconductivity measurements of Ce/sup 3 +/:YAG
Technical Report

OSTI ID:6904696
There does not seem to be any fundamental problem associated with using high intensity short duration pulsed laser sources for photoconductivity research. The observed photocurrent was linear with respect to both the applied electric field and the incident photon flux. No saturation effects of the photocurrent were observed at these applied electric fields and photon fluxes. The excited state photoconductivity experiment demonstrated the feasibility of such experiments as well as confirming that the strong excited state absorption transition in Ce/sup 3 +/:YAG terminates in the YAG conduction band. The optical absorption from the 5d excited state led to an increase in the photocurrent which was due to an electron being promoted to the host conduction band.
