Replicate spectrum of white OLED in "Optimize Your OLED/LED in One Second" lecture


#1

Hello,
I am trying to replicate the spectrum of white OLED in “Optimize Your OLED/LED in One Second” lecture. Unfortunately, My simulation display bad result. I have two questions hope someone can help.

  1. I know that I used different material of ITO, is that the main reason for the wrong result?
  2. what is the thickness value of glass? If I set thickness of glass to zeros (as show in the lecture) still got the wrong spectrum.
    Here are my simulation file and expected spectrum. Thank you!

How to replicate correct result from paper?

Hi @1672862

I have the script files used in the webinar attached for your review:
library_spectra.lsf (8.0 KB)
7 whiteoled.lsf (2.4 KB)
library_materials.lsf (42.5 KB)

There are a few things that might affect the results that you are obtaining:

  1. Please use the material_library data to update the material indices.
  2. Use a refined mesh and make sure that dipole (shown by white rectangle) is completely located inside the single layer.
  3. Perform convergence testing: https://kb.lumerical.com/en/index.html?layout_analysis_test_convergence_fdtd.html

Please keep me updated if you had further inquires.
