The influence of PcCu layer crystalline structure on the temperature stability of SAW gas sensors

Abstract

The effect of temperature on the frequency shift of NO, SAW chemosensors has been studied. Copper phthalocyanine was used as the chemical interface. We have investigated the influence of crystalline sttucture of PcCu coating on the temperature frequency stability of SAW delay lines on STX-quartz and 1 2 8 O Y X lithium niobiate.change is much lower for the delay lines covered with It was found that the temperature generated frequency p-PcCu films than for the lines employing the a-PcCu layers of the same mass. This is valid for both used substrates.
