Model depicting energy transfer from disordered to ordered phase
For athermal
nucleation (all nucleation occurs at t=0) n=1
Substrate
Polymer
thin film
Formation of the
ordered phase depends on nucleation and growth
• 1st: Low absorption in ordered phase but efficient
PL
• 2nd: High absorption in
disordered phase and exciton migration to the ordered region (I.e., red arrows)
• One-dimensional growth increases relative PL
from 1st process
