Abstract

Recently, there has been a growth of interest in new phosphors preparation for high resolution X-rays imaging systems. Sol-gel method has been used to synthesize europium doped gadolinium and lutetium oxide films. Structural and optical results are investigated and discussed on both Gd ₂ O ₃ :Eu ³⁺ (5 mol%) and Lu ₂ O ₃ :Eu ³⁺ (5 mol%). Those films are crystallized into cubic phase and present a density of 7.1 g/cm ³ and 8.4 g/cm ³ for Gd ₂ O ₃ :Eu ³⁺ and Lu ₂ O ₃ :Eu ³⁺ respectively. Room temperature emission spectra using an excitation of 468 nm was used to obtain the intense red emission ⁵ D ₀ → ⁷ F ₂ (611 nm) of Eu ³⁺ . Scintillation properties at 611 nm are finally proved using X-rays excitation.
