Mishra, Vidyanshu

In this thesis, rare-earth-containing chalcogenides and oxychalcogenides were sought with the aim to identify new crystal structures and to evaluate their potential as optical and thermoelectric materials. They were synthesized in the form of pure microcrystalline powders and single crystals...
