Ansys SPEOS-Fluorescent Material
I started to learn Ansys SPEOS recently and I would like to know if anyone have any answers to the following two questions I have.
I have created a Fluorescent material type (polymer film) which includes quantum dots. The details which I have entered in the 'Fluorescence' tab in the material. Currently I have given a absorption spectrum range between 250-540nm and emission range from 500-1000nm for the quantum dot.
1) I would like to know what is this scattering variation graph which shows in the below figure. I would also like to know what is the wavelength range I need to give in the scattering variation so that the quantum dots will work. Does Ansys software automatically calculate the diffusion coefficient?
2) Currently I have 0.9% w/w of 5nm quantum dots in a polymer(density=1.5g/cm3). I have converted this to parts/mm3 so I can enter it to the software and I was wondering if below conversion is correct.
0.9% w/w = 9000ppm = 9000 e-6 mg/mm3 = 9000 e-9 g/mm3*1000/1.5g= 0.006/mm3
Thank You

Hello,
- The scattering variation graph is the diffusion (mm-1) depending on the wavelength, the range to set should correspond to the wavelength bandwidth that you have information of diffusion (visible range for instance?). Here is some additional information about this from the SPEOS User Guide. https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/Optis_UG_LAB/Optis/UG_Lab/scattering_properties_162668.html
- Regarding the second question - please check the following link.https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/Optis_UG_LAB/Optis/UG_Lab/particles_31533.html
I hope this helps answer your question.
Thank you.
