Published July 2019, 15 pages, 4 tables, 3 figuresPerovskite quantum dots (PQDs) have been developed in the past few years and are now coming to commercial prominence due to their excellent photophysical properties, low heavy metal content and low cost fabrication. Research publications on these materials have grown significantly after highly luminescent colloidal perovskite QDs were first reported in 2015. They possess exceptional optical properties including:
- high brightness
- tuneable emission wavelength
- high colour purity
- high defect tolerance.
PQDs are being developed as alternative down-conversion materials in phosphor-converted light-emitting diodes (pc-LEDs) for lighting and next-generation of display technology.

- Synthesis methods.
- Applications analysis including displays, photovoltaics and lasers.
- Challenges.
- Recent commercial activity.
- Producer profiles.
