Unity 2D: How to apply a glowing effect to 2D Sprite?

I would like to apply a glowing effect to a 2D sprite, in my case it is a Pong game with 2 paddles and a ball. I want the effect to seem as if the paddles and such 'glow in the dark' similar to how a black light illuminate objects. I want to note that I have already applied a texture the paddles, with a simple solid green and purple color. Will the texture have to change? Ideally I would like to create a particle effect to achieve the glow if possible.

Thanks in advance.
