Description of the Related Art Conventionally, an oxygen-sensitive paint known as an oxygen sensor has a photoexciting substance having an oxygen quenching property dissolved in an oxygen permeable resin such as vinyl chloride or polystyrene. This coating material is applied to the base material to make an oxygen sensor.However, in the sensor using this coating material, the contact between the photoexcited substance and oxygen depends on the diffusion phenomenon of oxygen in the resin, so the oxygen sensitivity depends on the temperature. However, there is a problem that the time response to pressure fluctuation is poor. Also, at low temperatures, the oxygen permeability of the resin decreases, so the sensitivity becomes extremely low, and trace oxygen detection in the upper atmosphere environment, minute pressure measurement on the object surface, and pressure distribution on the surface of the specimen in the low temperature wind tunnel. It could not be used for measurement.

We have proposed a method of directly adsorbing and holding a photoexcited substance on a substrate, and a sensor prepared by using this method (Japanese Patent Laid-Open No. 11-242242).
-37944). The sensor by this method had high sensitivity and was extremely excellent in that the sensitivity did not decrease at low temperature, but the sensor base material suitable for forming the porous film was limited. There is also a problem that the operation of adsorbing a substance cannot be said to be easy for any specimen.

The horizontal axis represents emission wavelength, and the vertical axis represents relative change in emission intensity. The emission intensity rapidly decreases as the oxygen partial pressure increases, and the emission intensity ratio between the argon atmosphere and the oxygen atmosphere is about 476.

In addition, it was possible to obtain a highly functional pressure-sensitive paint that was unprecedented, with no time delay in response to pressure changes. As a result, it becomes a paint that can be used enough for pressure measurement in a low temperature wind tunnel such as liquid nitrogen temperature, and can be applied by a method such as spray coating, and an oxygen sensor can be easily made. became. Further, in the examples, the sensor is described as being cast on the frosted glass portion of the glass substrate and air-dried, or spray-painted on the aluminum plate with an air brush, but the pressure-sensitive paint itself is solidified without using these substrates. It can also be used as a sensor.
