Phosphors
Eu3+ is the stable form, but why do people have to go through the laborious task to reduce it to Eu2+ for phosphor application. And also kindly suggest a low temperature (not higher than 200oC)...

I am planning to using Eu2+ as a dopant, as this one is usually found in the +3 state and usually gets oxidised from +2 to +3 for Phosphor materials. I usually found it to be more useful in the +2...

I am looking for the structure of the host and the dopants. As we usually use Ce3+ and Eu2+ for both the colours, can we have a host with necessary added other dopants that can generate both. This...

I'm researching light sources and their UV emissions. I'm curious if a 50W, 7500K conventional LED lamp emits any UV light. I found that a 200W tungsten lamp can emit up to 1.5 mW/cm² at 350 nm....

I have an issue with SEM imaging of liposomes. When measured by DLS, they appear to be around 120 nm, but when using SEM with simple air drying, they appear much larger, around one micrometer.
