A chameleon luminophore: A temperature-sensing material is reported that has a high thermostability (see picture). The material is composed of color-changing luminescent coordination polymers containing EuIII and TbIII ions. The coordination polymer exhibits a high emission quantum yield Φ of 40 % at room temperature and a temperature-sensing ability over a wide range of 200–500 K.
