Nanothermometry: Temperature-Dependent Exciton and Trap-Related Photoluminescence of CdTe Quantum Dots Embedded in a NaCl Matrix: Implication in Thermometry (Small 4/2016)

Solid-state powders of CdTe quantum dots embedded in a NaCl matrix are applied as a highly sensitive probe for luminescence thermal imaging and sensing across a wide range of temperatures by A. L. Rogach and co-workers on page 466. They show how the emission color changes over the whole spectral range from green to red as a function of temperature, and demonstrate that the luminescence originating from both excitonic and trap-related recombination channels is temperature dependent.
