Abstract:

The investigation was concerned with the optical excitation of plasma radiation in a metal film and the detection of this radiation. The experiment was unsuccessful -- that is, with the available sources and detection equipment no radiation was observed in silver films of approximate thickness 300A, deposited on quartz and lithium fluoride substrates. While no radiation has as yet been detected, an indication of plasma oscillation has been observed in an absorption experiment. The absorption experiment made use of the Beckman DK-2A spectroreflectometer. The transmission of silver films of approximately 300A thickness was measured at several angles of incidence in the range 0 - 60 degrees, by inserting the samples on an improvised table just ahead of the integrating sphere. The effect is shown very well in the transmission curves and gives some confidence that with further improvements in the detecting system plasma emission might be seen.
