Colloidal quantum dots as classical and quantum light sources: Fundamentals and applications

Colloidal Quantum dots and other nanomaterials provide platforms for novel chemistries, spectroscopies, and technologies in a broad range of fields. In addition, knowledge gained from applying nanomaterials can provide insights and applications beyond the specific nanomaterial being studied. Spectroscopy focused at the single quantum dot level has uncovered fundamental electronic and optical properties that highlight the potential and challenges of broadly applying quantum dots in light emitting applications and as potential sources of quantum light. The broad color range and saturation of the emission from quantum dots has found application in a variety of technologies where classical luminescence is of interest, including displays and fluorophores for bio-medical imaging in the short-wave infrared. Recent results show that some colloidal quantum dot structures display highly efficient single photon emission with optical coherence times that are an appreciable fraction of their radiative lifetimes, pointing to their potential in quantum optical devices. This talk will cover both the fundamental spectroscopy behind colloidal quantum dots as light emitters, as well as a range of applications.
