Photopyroelectric characteristics of Pr6O11 - ZnO ceramic composites.

Characteristics of different Pr6O11 ceramic composites were studied using photopyroelectric spectroscopy. The amount of Pr6O11 in the composite was varied from 0.1 to 0.75 mol% at the sintering temperature of 1190 and 1270°C. It was found that optical energy band-gap (Eg) of the composite is reduced...
