Abstract:
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 bilayer system, highlighting the promising potential of colloidal QDs as flexible photonic components in next-generation optoelectronic technologies.
