Abstract
Radiative and optical properties of polycrystalline La1−x Sr x MnO3 (0≤x≤0.4) in the vicinity of the metal–insulator transition are presented. The temperature dependence of the total hemispherical emittance ε H of La1−x Sr x MnO3 was measured by the calorimetric method in the temperature range from 173 to 413K. It was confirmed that ε H showed unexpected variation as a result of changes in the hole concentration (x). Especially in the case of La0.825Sr0.175MnO3, ε H remains high above the transition temperature T C due to insulator-like behavior; on the other hand, it decreases sharply below T C because of metallic behavior. The spectral reflectance was measured by FT-IR in the wavelength range of 0.25 to 100 μm at room temperature. The optical constants were calculated by Kramers–Kronig analysis of the spectral reflectance data. An insulator-like character of the optical properties appears at lower Sr2+ doping levels while a metallic one exists at higher Sr2+ doping levels.
