Triple Matrix Confinement-Induced Ultrabright Afterglow From Carbon Dots With Multivariate Responsive Afterglow Colors for Advanced Dynamic Information Encryption. [PDF]
Angew Chem Int Ed EnglA novel carbon dots material (BUL‐CDs) with an initial afterglow brightness (406 cd m−2) far exceeding that of other afterglow luminescent materials was developed. Furthermore, the BUL‐CDs exhibited time‐dependent afterglow colors, excitation‐dependent afterglow colors, and thermochromic afterglow in response to triplet variables.

The behavior of irreversible thermochromic inks in the paper recycling process [PDF]
European journal of sustainable development research, 2021 Thermochromic printing inks are special chromogenic inks that change their color by exposure at a certain temperature, which is usually called the activation temperature (TA). The color change can be irreversible or reversible. The property of irreversible color change in relation to temperature exposure over time, allows the development of numerous ...
