Far infrared properties of bulk sintered and thin film Zn2SnO4
(Lausanne : Elsevier Science, 2007)
Room temperature far infrared reflectivity spectra of single phase spinel zinc-stannate thin films, prepared by rf magnetron sputtering on a glass substrate, and bulk sintered samples were measured. The sintered samples ...
Far infrared reflectance of sintered nickel manganite samples for negative temperature coefficient thermistors
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Single phase complex spinel (Mn, Ni, Co, Fe)(3)O-4 samples were sintered at 1050, 1200 and 1300 degrees C for 30 min and at 1200 degrees C for 120 min. Morphological changes of the obtained samples with the siDtering ...
Far infrared properties of PbTe doped with cerium
(Lausanne : Elsevier Science, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...
Effect of ageing on optical and thermal properties of YBa2Cu3O7–δ
(International Journal of Materials Research, 2007)
Photoacoustic phase and amplitude spectra of YBa 2 Cu 3 O 7 – δ samples synthesised 18 years ago were measured and numerically analysed. The value of thermal diffusivity obtained on the aged samples was lower than the ...
