The construction of smart materials, especially white light emitting (WLE) hydrogels with multi-stimuli responsive properties, has received widespread attention from researchers. In this study, a WLE hydrogel was obtained by the in situ doping of Eu3+ and Tb3+ into a blue emission low molecular weight gelator (MPF). Remarkably, the prepared WLE hydrogel possessed excellent stimuli responsiveness to pH, temperature and chemicals, and could be used as a soft thermometer and a selective sensor for Cu2+. The correlated color temperature of the WLE hydrogel was calculated to be 5063 K, suggesting a...
