Аннотация: <jats:p> Lead-free halide double perovskite Cs <jats:sub>2</jats:sub> AgInCl <jats:sub>6</jats:sub> has become the research hotspot in the optoelectronic fields. It is a challenge to utilize the lattice doping by different lanthanide ions with rich and unique photoluminescence (PL) emissions for emerging photonic applications. HereПоказать полностью, we successfully incorporated Dy <jats:sup>3+</jats:sup>, Sm <jats:sup>3+</jats:sup>, and Tb <jats:sup>3+</jats:sup> ions into Cs <jats:sub>2</jats:sub> AgInCl <jats:sub>6</jats:sub> nanocrystals (NCs) by the hot-injection method, bringing diverse PL emissions of yellowish, orange, and green light in Cs <jats:sub>2</jats:sub> AgInCl <jats:sub>6</jats:sub> :Ln <jats:sup>3+</jats:sup> (Ln <jats:sup>3+</jats:sup> = Dy <jats:sup>3+</jats:sup>, Sm <jats:sup>3+</jats:sup>, Tb <jats:sup>3+</jats:sup> ). Moreover, benefiting from the energy transfer process, Sm <jats:sup>3+</jats:sup> and Tb <jats:sup>3+</jats:sup> ion-codoped Cs <jats:sub>2</jats:sub> AgInCl <jats:sub>6</jats:sub> NCs achieved tunable emission from green to yellow orange and a fluorescent pattern from the as-prepared NC-hexane inks by spray coating was made to show its potential application in fluorescent signs and anticounterfeiting technology. This work indicates that lanthanide ions could endow Cs <jats:sub>2</jats:sub> AgInCl <jats:sub>6</jats:sub> NCs the unique and tunable PL properties and stimulate the development of lead-free halide perovskite materials for new optoelectronic applications. </jats:p>
