Photopyroelectric spectroscopy (PPES) is used to study the band-gap energy, Eg, of ZnO doped with 1 mol% MnO and 0 – 2.0 mol% of Er2O3 sintered at isothermal sintering temperatures, 1200 and 1300⁰C. The wavelength of incident light is kept in the range from 300 to 800 nm and the PPE spectrum with re...
