Photopyroelectric spectroscopy is used to study the band‐gap energy of the ceramic ZnO+0.5 Bi2O3+0.5 TiO2+0.4 Co3O4 (mol%), sintered at the isothermal temperature 1180 and 1210, 1240, 1270, 1300° C for 1 and 2 hours in air. The wavelength of incident light, modulated at 9 Hz, is kept in the range 30...
