The light emission time response of quenched NE1T1 plastic scintillators has been measured using a streak camera (20 ps resolution) and 100 to 180 ps, 1.06 um, laser-produced, pulsed, low energy x-ray excitation. Each light output pulse was obtained by deconvolutlon from the film data using the x-ray temporal response measured with an x-ray sensitive streak camera (10 ps resolution). Time response parameters are presented for benzophenone and acetophenone, quenching agents which most

Results are given for unquenched samples consisting of different concentrations of butyl-PBD in PVT and for the phosphor ZnO doped with Ga.
