Spatially Resolved Energy Transfer in Patterned Colloidal Quantum Dot Heterostructures

摘要

Spatial uniformity is a key consideration in high-resolution displays and light-emitting structures fabricated from colloidal quantum dots (QDs). We report spatially and spectrally resolved transient photoluminescence measurements of laterally patterned QD heterostructures. "We show, using a microcontact printing technique, that spatially uniform energy transfer can be achieved in a QD donor-acceptor Mayer system, highlighting the promising potential of colloidal QDs as flexible photonic components in next-generation optoelectronic technologies.
