Why does a green laser not illuminate a glow in the dark object?

Question Description

In class, we had a demonstration where we turned off the lights and shined a green laser, then blue laser, at a glow in the dark object. The blue electrons stuck and illuminated the object while the green did not have any impact. Why? 

Final Answer

Green lasers are far more powerful than blue, but don't illuminate glow-in-the-dark objects.
