I'm trying to figure out which layers of the sun emit different types of radiation

For instance; I know that most of the visible light is emitted from the photosphere but what about IR, UV, x-ray, etc...?

Anyone know?

This article discusses the layers and what is emitted from some of them:

It appears that higher energy particles come from the interior and as they exit through the other layers interact and produce lower energy particles so your question of what layers emit what particles may be more nuanced than you expect.

The energy of the sun is born from nuclear reactions deep in the interior. The photons start out in the gamma ray energy range. As the photons work their way to the surface, they undergo many scatterings before they escape. The net result is a black body spectrum of approximately 5500 deg. C.
