  • Apr 2024
A series of lithium niobate crystals co-doped with uranium and indium was successfully grown by the modified vertical Bridgman method for the first time. With increasing In3+ ion doping concentration, the segregation coefficient of uranium and indium progressively deviated from 1. The structural refinement indicated that uranium ions with high vale...

  • May 2023
A series of Eu³⁺-doped Ca3Tb7(BO4)(SiO4)5O red phosphors with apatite structure have been synthesized via high-temperature solid-state method. It could be concluded from XRD results that pure Ca3Tb7(BO4)(SiO4)5O: Eu³⁺ phase was obtained. The structure refinement results confirmed that the space group of Ca3Tb7(BO4)(SiO4)5O: Eu³⁺ was P63/m and Eu³⁺...

... Scholars have posited that humanity is progressing toward a lithium niobate valley [7]. The PR effect in LN underpins platforms for applications such as holographic data storage [8] and real-time dynamic displays [9], marking a significant stride in the utilization of this versatile material. The intrinsic and extrinsic defects always serve as the PR centers. ...
