Homogenous Fluorescent Solution

[corvus corax]

Heyo.
I'm looking for a white fluorescing dye in the 380-400nm excitation range. It needs to be combined with heavy mineral-oil such that the resulting solution is tenaciously homogenous and will not separate out when centrifuged.
Many thanks,

Define "white" and "tenaciously homogenous". If you mean white as perceived by the human eye, it seems to me that a mix of red, green and blue fluorescing dyes would work. Soluble dyes won't settle but how stable these are over time is questionable.

Yeah, fair enough:
So as far as the fluorescing color goes, I would be looking for white as perceived by an observer.
When I say tenaciously-homogenous, what I mean is that the solution could have a tendency towards homogenous distribution of its constituents when left alone. The particles would always tend to have random distribution throughout the volume of the mineral-oil.

So a mixture of three different colors would work as well.

You are saying that soluble fluorescent dyes would work for you. You don't need particles at all.

Most washing powders contain such a mixture of fluorescent dyes giving the impression of white light.
