摘要：

Two types of sensitive high-T(c) bolometer have been fabricated on 20-mum-thick sapphire substrates with YBa2Cu3O7-delta thin film transition edge thermometers. The sensitivity of both devices is superior to commercially available, room temperature pyroelectric detectors. A 1 X 1 mm bolometer with a radiation absorber of gold black smoke has a noise equivalent power NEP=2.4 X 10(-11) W/Hz1/2 at 10 Hz and has useful sensitivity over wavelengths 20-100 mum. A 3 X 3 mm bolometer with a Bi film radiation absorber has NEP=3.6 X 10(-10) W/Hz1/2 at 10 Hz and has useful sensitivity over wavelengths 100-300 mum. Water vapor transmittance spectra were measured to demonstrate the sensitivity of both devices.
