ABSTRACT=<p>The design of molecular materials suitable for disparate fields could lead to new advances in engineering applications. In this work, a series of Ln<sup>3+</sup>-doped BiF<sub>3</sub> sub-microparticles were synthesized through microwave-assisted synthesis. The effects of doping are evaluated from the structural and morphological viewpoint. In general, increasing the Ln<sup>3+</sup> concentration the octahedral habitus is distorted to a spheric one, and some aggregates are visible without any differences in the crystalline phase. The optical response of the samples confirms that the BiF<sub>3</sub> materials are suitable hosts for the luminescence of the tested trivalent lanthanide (Ln<sup>3+</sup>) ions (Ln = Eu, Tb, Tm, Ho, Er, Yb). A Yb<sup>3+</sup>/Er<sup>3+</sup> co-doped sample is presented as an illustrative example of all-photonic molecular logic operations and primary luminescent thermometry.</p>
