| Abstract: | The dielectric and pyroelectric properties of three crystals in the system of lead barium niobate(PBN) were investigated in the temperature range from 100K to 450K. They have a moderate pyroelectric coefficient, a relatively low dielectric constant and a relatively high figure of merit for pyroelectric detector, and therefore are suitable for applications in pyroelectric detectior. |
