Optimizing In Situ Tuning of Upconversion Photoluminescence Properties in PMNT Single Crystal via Structure Modulation and Sensitizer Doping
Upconversion photoluminescent materials play a pivotal role across various fields, necessitating the modulation of their photoluminescence (PL) properties to facilitate device miniaturization and integration. The in situ electrical tuning of PL properties in ferroelectric materials represents an innovative approach that has garnered considerable research interest. In this work, we optimized the electrical tuning of upconversion PL performance in Pb(Mg1/3Nb2/3)O3–PbTiO3 (PMNT) through a coordinated strategy involving structural optimization and sensitizer doping. This resulted in a remarkable enhancement ratio of upconversion PL (28%) under applied electric field. There is a decreased symmetry around Yb3+ ions in PMNT crystals, which in turn improves energy transfer efficiency. Our findings provide a novel framework optimizing the electrical modulation of upconversion PL performance via structural adjustments and sensitizer incorporation.
