Photons are elementary particles and are not made out of smaller things as far as we know. They are the fundamental particle of light (electro-magnetic radiation).

all electromagnetic radiation is emitted in little packets or quanta of energy. These quanta are more commonly referred to as photons. Even though photon covers any and all electromagnetic radiation, emissions, most people use the term photon to refer to the narrow band of frequencies of visible light.
If you are asking how a photon is created, it can be many sources depending upon which emission. For the visible light from the Sun, it is a result of the fusion of hydrogen into helium. To find specific processes for how each is created, you might try to search for each of the types of electromagnetic radiation such as gamma rays, X-rays, microwaves, visible light, UV, IR, radio , etc.

A photon is a manifestation of space.
It is a result of the quantum effect that came into existence when the first space-time pulse emerged

Photons -- that is, particles of light -- are massless, and that's why they can travel so fast. If you can determine what Photons are made of you might get the Nobel Prize.

Einstien worked on the quantum theory and concluded that heat or light radiations are in the form of energy units called
"quanta".If this energy is in the form of heat this energy unit is
called phonon and if this energy unit is in the form of light it is called photon.So you come to know that photon is not actually a materialistic particle but an energy unit.

The last I knew they were part of an atom. I guess that is electron and proton. A photon is the energy given off. Don't you have a textbook. Look it up in the back of the book under index. It might be in the glossary, which is just before the index or the bibliography. I could be wrong.
