I created my first copper-doped zinc sulfide phosphor today. After my success, I got online and found a preview of this book: Phosphor Handbook.
What I could view of the book was very insightful. However, though it seemed to glaze the subject, it did not completely answer my question.
How can I calculate the approximate wavelength to be expected from zinc sulfide doped with varying concentrations of activators and/or co-activators?
I have been playing with some numbers, trying to find a crude relationship between them. 4.7 eV for copper, 3.91 eV for zinc sulfide, 4.3 eV for zinc, 4.73 eV for silver... A peak emission of 530 nm for ZnS:Cu, 450 nm for ZnS:Ag...
I am sure the answer is obvious. I am just not seeing it.
I appreciate any help you guys can give me. Even if it is just something that can help point me in the right direction.
