Dear Colleagues,

Photoactive nanomaterials exhibit a myriad of customized properties, such as photon converting ability, specific surface area, physicochemical stability, chemical reactivity, and others, making them appealing for a wide range of practical applications. Photoactive nanomaterials can convert photon to photon (photoluminescence), heat (photothermal effect), and separated charged carriers (photovoltaic effect), which is very important for the manipulation and utilization of light.

This Special Issue aims to focus on recent progress and advances in emerging photoluminescent, photothermal, photovoltaic, and photocatalytic nanomaterials and their applications in optoelectronics and energy conversion. Optical design for enhancing light emission, photothermal effects, and photocatalytic materials will be covered. Further, the investigation of carrier dynamics of photoactive nanomaterials by ultrafast spectroscopy will be an important subject for this Special Issue.

The subtopics include (but are not limited to):

• Photothermal nanomaterials for applications in solar steam generation/solar–thermal–electric conversion;
• Photoactive nanomaterials for applications in photodetectors/solar cells/photocatalysts;
• Fluorescent nanomaterials for applications in bioimaging, optical sensing, LEDs, etc.;
• Anti-reflections, plasmonics, and photonic crystals for enhancing light harvest/emission;
• Carrier dynamics of the photoactive nanomaterials.
