Paper Abstract

The theory of Photoacoustic Piezoelectric (PAPE) technique has been developed for two-layered model. An analytical expression for the phase of output voltage versus modulation frequency has been obtained. The thermal diffusivity of Phosphor/PVA light-emitting composite material has been studied. PAPE technique has been employed successfully for investigating the thermal diffusivity of two-layered materials.
