Abstract

Abstract : A high-performance Cu-DABDT-based X-ray detector was fabricated where Cu-DABDT was synthesized by conjugating copper cations and DABDT ligands. Abstract : Here, we constructed Pb-free Cu-DABDT-MOFs-based (DABDT = 2, 5-diamino-1, 4-benzenedithiol) X-ray detectors. Combined with the advantage of high activation energy, the Cu-DABDT-MOFs-based detector can effectively generate and capture electrons under X-ray exposure and presents a high mobility–lifetime ( μτ ) product of 6.49 × 10 −4 cm 2 V −1 and promising detection sensitivity of 78.7 μC Gyair −1 cm −2 . As groundbreaking work, these discoveries have provided information for exploring MOF materials toward green and high-performance high-energy radiation detectors by exploiting the designable structure and tunable properties of the MOF family.
