Lyu, T. (author), Dorenbos, P. (author), Li, Canhua (author), Li, Silei (author), Xu, Jian (author), Wei, Zhanhua (author)It is challenging to rational design persistent luminescence and storage phosphors with high storage capacity of electrons and holes after X-ray charging. Such phosphors have potential applications in anti-counterfeiting and X-ray imaging. Here we have combined vacuum referred binding energy diagram (VRBE) construction, photoluminescence...journal article 2022

Lyu, T. (author)In this thesis, we have studied two types of charge carrier capturing and detrapping processes: (a) electron capturing and electron liberation; (b) hole<br/>capturing and hole liberation. Both the (a) and (b) processes can be utilized for the rational design of afterglow and storage phosphors in different compounds.doctoral thesis 2020

Lyu, T. (author), Dorenbos, P. (author)Developing a feasible design principle for solid-state materials for persistent luminescence and storage phosphors with high charge carrier storage capacity remains a crucial challenge. Here we report a methodology for such rational design via vacuum referred binding energy (VRBE) diagram aided band structure engineering and crystal synthesis...journal article 2020

Lyu, T. (author), Dorenbos, P. (author)Guided by vacuum referred binding energy (VRBE) diagrams, both the trapping and detrapping processes of electrons and holes are explored in the bismuth and lanthanide-doped LiRE(Si,Ge)O<sub>4</sub> (RE = Y, Lu) family of compounds. The Tm<sup>3+</sup> electron trap has been combined with the deep hole traps of Ln<sup>3+</sup> (Ln = Ce, Tb, or...journal article 2020

Lyu, T. (author), Dorenbos, P. (author)We report a general methodology to the rational design of thermally stimulated short-wave infrared (SWIR) luminescence between ∼900 and 1700 nm by a new combination of using efficient energy transfer from Bi <sup>3+</sup> to Nd <sup>3+</sup> and an adjustable hole trap depth via valence band engineering. Predictions from a vacuum referred...journal article 2019

Lyu, T. (author), Dorenbos, P. (author)The vacuum referred binding energy (VRBE)-guided design of Bi<sup>3+</sup>-based storage and afterglow materials together with charge carrier trapping processes is explored with a study on bismuth- and lanthanide-doped rare earth ortho-phosphates. By combining Bi<sup>3+</sup> with the shallow hole trap of Tb<sup>3+</sup> or Pr<sup>3+</sup>,...journal article 2018

Lyu, T. (author), Dorenbos, P. (author)Various methods for deliberate design electron and hole trapping materials are explored with a study on double lanthanide doped rare earth ortho phosphates. Cerium acts as recombination center while lanthanide codopants as electron trapping centers in LaPO4:0.005Ce3+,0.005Ln3+. The electron trap depth generated by lanthanide codopants can be...journal article 2017
