Bulk-like emission in the visible spectrum of colloidal LiYF₄:Pr nanocrystals downsized to 10 nm.

ABSTRACT: Though Pr³⁺ doped LiYF₄ (LiYF₄:Pr³⁺) bulk crystals are a well-known laser gain material with several radiative transitions, their nanocrystal counterparts have not been investigated with regards to these. Through downsizing to the nanoscale, novel applications are expected, especially in composite photonic devices. For example, nanocrystals in stable colloidal form with narrow size distribution are highly desirable to reduce scattering in such composites. Herein, we synthesized monodispersed LiYF₄:Pr³⁺ nanocrystals having a size of 10 nm resulting in colorless clear stable colloidal dispersions and conducted an extensive optical characterization for the first time. We observed unexpected yet intense emission with excited sta
