A fluorescent substrate includes a base having a reflective surface and a flat bottom surface, and a fluorescent layer disposed on the reflective surface of the base such that the reflective surface of the base directs, outward from the wheel, fluorescence emitted from the fluorescent layer due to its excitation by exciting light. In addition, the spent germ can serve as a carrier for such biomaterials. The structures are then trimmed and the seed material is plated to form wiring on the sidewalls of the structures. Furthermore, a coaxial cable 9 is connected to both ends of the matching-dedicated variable capacitor 5. The system architecture allows an incoming optical signal to be directed through any desired combination of optical components via multiple traversals of the switching fabric. In order to dilute the added reaction hydrogen, the process makes use of non-reactive compounds such as N2, CH4, C2H6, C3H8, C4H10, Group VIII noble gases as well as admixtures of same in any amount, in gas or vapor phase.
