Photon Quartz is very important in Phantasy Star Online 2, primarily used for Augment Capsule exchanges and Multi-Weapons, you probably won't need as many of these as the other materials, and they are more abundant as-is. Let's take a look at how to get Photon Quartz in Phantasy Star Online 2.

Photon Quartz is found all over the place, a good specific spot are along the boundaries of the Halphana Wetlands in Northern Aelio
Unlike Photon Chunks, Photon Quartz is found pretty much anywhere except South Aelio. If you find yourself with some favorite routes to gather other materials, you'll probably be picking up Photon Quartz along the way. In case you do need some quick, I find it best to head to the areas in North Aelio where Trinite can be found to gather a bunch of Photon Quartz as well.
North Aelio in general is the greatest source of both Quartz and Trinite, at least in the beginning of PSO2 New Genesis, therefore farming both of them at the same time is highly suggested.
While Trinite looks like a blue-ish egg, Photon Quartz is a teal, spiky crystal which you can identify from far away, due to how distinct its appearance is. Just run in circles in the specified areas, and you will be finding the specific mineral in loads.
Unfortunately, Photon Quartz is not yet tradeable making it an ingredient of higher value in general. This is the reason why you will need to spend some time farming the specific item, and since Player Shops are still not working properly, you are not even able to buy some directly. This requires you to have a large amount of PSO2 NGS Meseta, which is the currency in "Phantasy Star Online 2: New Genesis".
