✦ Synopsis
Communications cut-off filters (RG 610 nm for PtOEP, OG 590 nm for [Ru(4,,]CI2) were placed in front of a liquid-nitrogen cooled CCD detector (Model LN/CCD, Princeton Instruments, Inc.), with 578 x 384 pixels in a cell size of 13.25 x 8.83 mm'. Luminescent light from the sample surface was collected with a camera lens (Nikon, 55 mm, 1:1.2) and an imaged formed on the CCD camera. The pressure of the sample chamber was measured using a pressure gauge (Model FA 233, Wallace & Tiernan) with an accuracy of 5 0.1 psi.
Trichloroethane was used as the solvent to dissolve the dyes and the polymer 3. The dye concentration in the polymer matrixes ranged from 10 to 1000 ppm. Solutions containing the dye and polymer were spray coated onto the surface of interest. Some of the surfaces were precoated with an epoxy primer of a two-part system based on Super One-Coatm White D3400 and Glass Activator D3498 supplied by Pratt & Lambert. The dye film itself was very thin (between 5 and 15 pm) except for the measurements shown in Fig. . Samples were placed in a small pressure chamber. The adjustment of the pressure was achieved using a vacuum pump and compressed air. All the measurements were made at room temperature (25 f 1 "C). Response times for the sensing films were measured by switching the gas stream alternately between air and nitrogen.
