抄録

In order to develop a thermal radiation detector that can be used as a reference to measure optical radiation power and the spectral responsivity of a radiation detector, we investigated gold-back radiation absorbers. The spectral responsivity of the thermal radiation detectors are determined by the optical and thermal properties of the absorbers. The thermal radiation detectors consist of polyvinylidene fluoride (PVDF) pyroelectric film with the absorbers. The gold-back is prepared by evaporating gold in an oxygen-free nitrogen atmosphere and deposited on the Al electrode of the PVDF pyroelectric film. The nitrogen pressure was varied from 0.5-3 torr and the surface density of the deposited gold-black was varied from 0.02-1mg/cm2.<BR>We found that a gold-black radiation absorber prepared by evaporating gold in a nitrogen pressure of 1.5 torr and depositing it to a thickness of 11μm, the gave the highest spectralpresponsivity, which was constant within 1% over a wavelength region of 200-600nm.
