    $\begingroup$ change the diffuse shader for an emission shader. $\endgroup$ – user1853 Dec 27 '17 at 3:45

Cycles works with shaders that describe the interaction with light.

BSDF shaders Describe light reflection, refraction and absorption at an object surface.

For more info read: What is a BSDF? and https://docs.blender.org/manual/en/dev/render/cycles/materials/surface.html#bsdf-parameters

A Diffuse BSDF shader does not emit light.

You need a shader that does! So use an

Emission shader

Used to describe light emission at an object surface or in a volume.
