Colloidal semiconductor nanomaterials (e.g., CdSe colloidal quantum dots or colloidal nanoplatelets) with controlled size, shape, and composition in a simple chemistry process are crucial in today’s optoelectronic devices. Fundamental problems with size, shape, structure (core/shell, core/crown/shell) and surface chemistry define the properties which are tailored for specific applications. Strong quantum confinement effect allows strong spontaneous emission for light emitting diodes; while engineering the confinement configuration (type II hetero-structure) can allows optical amplification at lower thresholds. Also by well adjusting the band structures with adjacent layers, colloidal semiconductor nanomaterials can show high performance as photovoltaics or photodetectors. To address these attractive issues, the symposium will cover the general topics from colloidal semiconductor nanoparticle synthesis, functionalization, characterizations, and applications in optoelectronics and photonics. Specifically, this symposium will focus on the topics as follows.

• Novel nanomaterial synthesis and characterization.
• Colloidal quantum dots and their LEDs performances.
• Colloidal quantum dots and their laser demonstrations.
• Quasi-2D nanomaterials (colloidal nanoplatelets) and their assembling structures with surface modifications.
• Colloidal nanoplatelets and their LEDs performances.
• Colloidal nanoplatelets and their structure’s engineering for low threshold lasers.
• Large area integration of nanoparticle assembly, patterning, and coatings for optoelectronic applications.
• Colloidal nanomaterials and their applications in photovoltaics, photodetectors and other optoelectronic devices.
• Advanced spectroscopy and transport studies on carrier dynamics, energy transfers and charge separation processes of nanoparticles and their assemblies.
