thats a big ass ball. What size is it?

Try charging the phosphors with the blue laser, or leaving it in direct sunlight for a few minutes.
THEN expose the phosphors to high intensity RED light from a red laser or high intensity red LED.
When I did this to a large sheet of glow material (OSHA requirement) I was able to remove or negate the stored glow where I aimed the light. The effect is not as intense and when done in a fully dark room your irises will not re-compensate quickly to room darkness after turning off the red light.

This, people, is what cats see whenever there is a laser light. They are mesmerized by not just the dot, but also the lines. So don't blame them!

Now just paint an entire wall or ceiling with some glow in the dark paint, and you're in business :D

Oh and dont get mixed up with power and brightness. Power is a measure of the intensity of light, as in how much of the light there is, more power, more photons. Brightness is obviously affected by power, but it is even more so affected by the human eye's sensitivity to different wavelengths. Green appears much brighter than red or blue. A 5mW green can be brighter than a 30mW red, even though the red laser is actually more powerful. But also energy per photon is dependent on wavelength alone.
