Modeling Energy Migration for Upconversion Materials

One of the key issues in upconversion materials is the design of an appropriate complex nanoarchitecture to control energy migration. We propose here a numerical tool based on a Monte Carlo approach capable of modeling the energy migration in particles with diameters of up to a few tens of nanometers. To validate the approach, the obtained results are compared with a wide range of published experimental data. The proposed simulation allows us to guide the optimal design strategies to develop upconverting nanoparticles for light-harvesting applications.
