A functional material is a term used for a material with properties that fit a specific application. These properties can be intrinsic to a material, or the material can be tuned for obtaining the desired properties. Some materials can be used by themselves as functional materials, while others support functional materials. Zeolites are nanostructured porous materials that can be used as functional materials or used as supports for other functional materials. Quantum dots are luminescent materials with plenty of applications such as biomarkers, photocatalytic degradation, or biocides. However, the use of quantum dots is limited by the effect of moisture or heat on them. The applications of quantum dots can be improved if proper support is used. In this work, a brief overview of the use of zeolites as supports for quantum dots is offered, and their applications in optical devices are discussed.
