Visible colorimetric dosimetry of UV and ionizing radiations by a dual-module photochromic nanocluster

open access: yesNature Communications, 2021
Radiation dosimeters that measure ionizing radiations over a broad range and allow for direct readout are desirable. Here, the authors present a dual-mode photochromic thorium-based metal-organic nanocluster that enables direct visible colorimetric ...
