- W2085608349 abstract "Variation of Photo-electric Effect with Temperature, to 420ifmmode^circelsetextdegreefi{}.---(1) Pt filaments coated with oxides of Ba and Sr were mounted in an evacuated tube with a quartz window and could be heated electrically to any desired temperature. The photo-electric current received by a copper oxide coated Faraday cylinder when a strip was illuminated with light from a quartz arc was measured with a sensitive electrometer, and was found to increase rapidly with the temperature reaching a value, on first heating to 420ifmmode^circelsetextdegreefi{}, about 68 times as great as at 20ifmmode^circelsetextdegreefi{}. The long wave-length limit was found to shift with increasing temperature from 2860 to about 3800 AA{}, the corresponding work function changing from 4.31 to 3.24 volts. On cooling, however, the sensitiveness and wave-length limit did not return to their original values, except very gradually, showing marked time-lag effects, due probably to changes in the oxide surface. (2) Pt strips, uncoated, were tested in the same manner. After preliminary treatment by repeated heating to 900ifmmode^circelsetextdegreefi{}, the current was found to be independent of the temperature to 500ifmmode^circelsetextdegreefi{}, except for a slight decrease due to the magnetic effect of the heating current, and the long wave-length limit remained constant within one per cent. at 2570 AA{}. Hence the work function or work necessary to detach an electron photoelectrically from Pt comes out 4.80 volts, which is close to the values found for the corresponding thermionic work function.Relative Energy of Spectrum Lines of Hg, 2301 to 2804 AA{} from an arc in quartz, after dispersion by a quartz spectrograph, was determined with a Coblentz thermopile.Variation in Resistance of Pt with Temperature to 600ifmmode^circelsetextdegreefi{} was measured (Table I.)." @default.
