Abstract
YBa,Cup superconductor orthorhombic-to-tetragonal structure phase transformation are measured. The infrared emission spectra with temperature increase show that the phase transformation occurs at 800K. The superconductivity of the sample disappear at 1000K. Rare earth sesquioxides infrared emission properties are measured. At 521 cm , , a new peak, appears in the infrared emission spectra and is split into two peaks at 528 cm and 517 cm at 1100K. The A-C-B structure phase transformation in relation to the infrared spectrum change is discussed.
