General description

Sodium terllurite is an alkali tellurite that is majorly used in the formation of glasses due to its unique properties which include good transmittance, refractive index, and high chemical resistance. It can be used as a tellurite source for the preparation of quantum dots.

Herein, a core-shell tellurium-selenium (Te-Se) nanomaterial with polymer-tailed and lateral heterojunction structures is developed as a photothermal absorber in a bionic solar-evaporation system. It is further revealed that the amorphous Se shell surrounds the crystalline Te core, which not only
