The pH-dependent reactions in the sonochemical synthesis of luminescent fluorides: The quest for the formation of KY(3)F(10) crystal phases
In this study Eu(3+)-doped yttrium fluorides were designed by ultrasound-assisted processes at different pH values (4.0–9.0). This novel strategy has enabled to obtain materials with intriguing morphologies and modulated crystal structures: α-KY(3)F(10), δ–KY(3)F(10)·xH(2)O, and Y(OH)(3–)(x)F(x). To...

description | In this study Eu(3+)-doped yttrium fluorides were designed by ultrasound-assisted processes at different pH values (4.0–9.0). This novel strategy has enabled to obtain materials with intriguing morphologies and modulated crystal structures: α-KY(3)F(10), δ–KY(3)F(10)·xH(2)O, and Y(OH)(3–)(x)F(x). To date, the literature has primarily focused only on the α-phase of KY(3)F(10). Yet, explaining the formation of the mostly uncharted δ-phase of KY(3)F(10) remains a challenge. Thus, this paper offers the key to synthesizing both the α and the δ-phases of KY(3)F(10) and also reports the first ultrasound-assisted process for the preparation of yttrium hydroxyfluorides. It is also unraveled the connection between the different pH-dependent reactions and the formation mechanisms of the compounds. In addition to this, the unique features of the Eu(3+) ion have allowed to conduct a thorough study of the different materials and have endowed the compounds with photoluminescent properties. The results underscore a highly tunable optical response, with a wide gamut of color emissions (from orangish to red hues), lifetimes (from 7.9 ms to 1.1 ms) and quantum efficiencies (98–28%). The study unveils the importance of sonochemistry in obtaining luminescent fluorides with controlled crystal structures that can open up new avenues in the synthesis and design of inorganic materials. |
