“…Subsequently, coalescence between these islands structure occurs, and array structure could be observed eventually. [63,64] In 1969, Bates first observed the microcolumnar array structure of CsI. [65] Subsequently, Fujieda and co-workers systematically investigated the influence of various deposition parameters including temperature, deposition rate, and subsequent annealing treatment on the formation of array structure.…”

“…To fabricate the desired structure, Tan and co‐workers investigated the array formation and the related parameter such as deposition rate( Figure a,b). [ 64 ] They revealed that CsI array generally grows along the original crystal orientation. The holes or cracks may affect final orientation, and an excessive deposition rate may cause column collapse or dual crystal orientation.…”

Scintillators, which can convert high‐energy ionizing radiation into visible light, have been serving as the core component in radiation detectors for more than a century of history. To address the increasing application demands along with the concern on nuclear security, various strategies have been proposed to develop a next‐generation scintillator with a high performance in past decades, among which the novel approach via structure control has received great interest recently due to its high feasibility and efficiency. Herein, the concept of “structure engineering” is proposed for the exploration of this type of scintillators. Via internal or external structure design with size ranging from micro size to macro size, this promising strategy cannot only improve scintillator performance, typically radiation stopping power and light yield, but also extend its functionality for specific applications such as radiation imaging and therapy, opening up a new range of material candidates. The research and development of various types of structured scintillators are reviewed. The current state‐of‐the‐art progresses on structure design, fabrication techniques, and the corresponding applications are discussed. Furthermore, an outlook focusing on the current challenges and future development is proposed.
