What Strategies Are Used to Mitigate Thermal Quenching?
Several strategies are employed to mitigate thermal quenching in nanomaterials:
1. Surface Passivation: Coating the nanomaterials with a shell of another material can reduce non-radiative recombination pathways. This is commonly seen in core-shell quantum dot structures.
2. Material Engineering: Developing materials with lower phonon energy can help in reducing non-radiative losses. For instance, using inorganic nanomaterials with high thermal stability can be beneficial.
3. Temperature Management: Incorporating efficient heat dissipation mechanisms, such as thermal conductive substrates or heat sinks, can aid in maintaining lower operational temperatures.
4. Doping: Introducing impurity atoms (dopants) that either trap charge carriers or modify the electronic structure can help in maintaining luminescence efficiency at higher temperatures.
