Photoacoustic, Piezoelectric sensors, Quantum EfficiencyAbstract
In this paper we present the study of three sensors, based on piezoelectric polymer thin films, for photoacoustic systems used in the characterization of liquids. Its performance was compared by carrying out measurements on well-known liquids. From the measured data, the sensitivity, noise level and quantification limit of each of the sensors were determined. The device with the best characteristics was used in the determination of the quantum efficiency of two dyes: Rhodamine 6G and Rhodamine B. The measured values agree very well with those reported by other authors.
