I would start with a black background. It should be possible to make very
visible spheres with good colors - that back light should even help to
define their edges (providing I placed it well, but I didn't test the code I
gave you).

What color are you using for your spheres?

It's possible to turn the spheres into light sources, but that won't make
them any brighter (they'll brighten up other nearby things, but that's
probably not what you want). That's a bad idea though, since it will really
slow things down with a lot of spheres. Emitting media is a better choice,
but first let's just see if we can create the effect you want through a
pigment.
