Semiconductor nanocrystals, also known as quantum dots, are tiny particles characterized by their narrow tunable emission and unique optical and electrical properties that attract a wide range of applications, ranging from fluorescence imaging to optoelectronics.

Thanks to the advances in colloidal synthesis techniques, semiconductor nanocrystals can be controllably synthesized with different sizes, shapes and dimensionality tailored for specific application. 

A distinguished class of semiconductor nanocrystals of mixed dimensionality (0D-1D) is semiconductor seeded nanorods or the dot-in-rod nano-heterostructures, characterized by large extinction coefficient, engineered Stokes shift and excellent PL properties; highly efficient light harvesting capacity and highly intense emission.

Semiconductor nanocrystals have shown promising potential for applications such as:

• Lighting and Display Technology
• Liquid Crystal Technology (LCD)
• Light Emitting Diodes (LEDs)
• Amplified Spontaneous Emission (ASE)
• Photovoltaics (PV) and Solar Concentrators
• Fluorescence Imaging and Detection
• Biosensing through Energy Transfer 
• Fluorescence Pull-Down Assays
• Fluorescence Multiplexing
• and a lot more!
