Oscillation features of the thermal radiation from a heated crystal plate

The presented results show that the spectrum of thermal radiation from a semiconductor plate whose opposite faces are parallel to each other demonstrates an oscillating character. This is due to the interference effects in the Fabry-Perot resonator. The spectrum features strongly depend not only on the plate thickness, but also on such parameters as plasma frequency (\omega_{\ab{p}}) and damping coefficient (\gamma_{\ab{p}}). The electron-hole plasma frequency can be easily varied by photo-excitation, injection of electrons or holes, and other techniques. So one can hope that the study of thermal radiation from such semiconductor elements would allow developing new efficient and controlled IR radiation sources

New materials for luminescent scanning near-field microscopy

Results on synthesis and characterization of the luminescent probes for applications in determination of near-field optical characteristics and spatial distribution of local temperature are presented. Two types of materials are studied: Eu³⁺ doped vanadates LaVO₄, and chromium-doped composites (NaAl(MoO₄)₂/Al₂O₃):Cr. It was shown that submicron-sized particles of the mentioned materials can be used for development of the luminescent probes for near-field optical applications
