Recent advances in tellurite molybdate/tungstate crystals

Abstract

Transition-metal oxides with special optoelectronic properties have received extensive attention and have been the subject of research studies in recent decades. In particular, tellurite molybdate/tungstate materials have exhibited multifunctional optoelectronic properties, which attracts considerable academic interest. Under the second-order Jahn–Teller effect, compounds with non-centrosymmetric structures including d₀ transition metals and cations with lone-pair electrons have been a hotspot in materials research. In recent years, a series of tellurite molybdate/tungstate crystals have been grown successfully. Research on structure–property relationships, physical properties and electric/optical devices especially in the mid-infrared range has developed rapidly. In this work, recent advances in tellurite molybdate/tungstate crystals are reviewed.
