Growth of Luminescent Films of Lutetium Oxide
Abstract:
Due to its high density and cubic structure, Lutetium oxide (Lu2O3) has been extensively researched for scintillating applications. Present manufacturing methods, such as hot pressing and sintering, do not provide adequate imaging resolution. Vapor deposition has been investigated as an alternative manufacturing method. Lutetium oxide transparent optical coatings by magnetron sputtering offer a means of tailoring the coating for optimum scintillation and resolution. Structural defects in the sputtering process adversely affect transparency and scintillation, and are critical in growing stress free, thick coatings. The effect of process parameters on the growth of magnetron sputtered Lutetium Oxide coatings will be presented and discussed.
