“…The variation is around 50 nm, the material appearing blue‐violet under UVC radiation, violet under UVB and pink under UVA. This mix was subsequently used to produce a flexible tape, using a modified version of the method presented by Abhinay et al., [ 65 ] and with the aid of a stencil the acronym IMC was made using three different UV wavelengths (Figure 5c). The different colors of the letters are apparent.…”

Photochromic sodalites are considered for a plethora of possible applications, such as UV indexing and X‐ray imaging, but for many of these the materials are yet to be optimized. UV indexing can be improved through incremental adjustment of the activation energy of coloration from 300 to 410 nm through replacement of sulfur with selenium. By combining this and other methods of tuning presented in the literature, the excitation threshold and photochromism color can be tuned independently of one another. The range of possible absorption maxima is expanded to 420–680 nm, or almost the entire visible spectrum. Mixing low‐cost and easy‐to‐synthesize sodalites further broadens the possible range of colors and facilitates development of a unique sodalite mix capable of quantifying the doses of two types of UV radiation simultaneously. Finally, the response to X‐rays of these highly tuned sodalites is investigated, and it is found that they can be sensitized to produce clear, high‐contrast X‐ray images at significantly lower doses of radiation than those required by classic photochromic sodalite, Na8(AlSiO4)6(Cl,S)2.

“…The hackmanite powders were cast as 80 mm-thick flexible green tapes in order to fix them easily to their positions in the exposure chamber, and also to measure their reflectance spectra easily. The tape-casting process is modified from that presented in the study of Abhinay et al 16 As can be seen from the starting reagents and the final composition of the synthesized products, these materials are non-toxic and environmentally friendly, consisting of elements that are abundant in nature.…”

Hackmanites, a variety of sodalite with the general formula Na8Al6Si6O24(Cl,S)2, are a family of nature‐based smart materials having the ability for reversible photochromism upon UV or X‐ray exposure. Being nontoxic, cheap, and durable, hackmanite would be an optimal material for the visual detection of the presence of X‐rays in simple portable systems. However, its X‐ray‐induced coloring abilities are so far known only qualitatively. In this work, a combination of experimental and computational methods is used to reveal the mechanism of X‐ray‐induced color changing in these materials. Finally, their use is demonstrated both in color intensity‐based X‐ray dosimetry and photochromic X‐ray imaging.
