Photoluminescence imaging of europium (III)‐doped γ‐Al2O3 nanofiber structures

摘要: Aluminium oxide (Al2 O3 ) has widely been used for catalysts, insulators, and composite materials diverse applications. Herein, we demonstrated if γ-Al2 was useful as a luminescence support material europium (Eu) (III) activator ion. The hydrothermal method post-thermal treatment at 800°C were employed to synthesize Eu(III)-doped nanofibre structures. Luminescence characteristics of Eu(III) ions in Al2 matrix fully understood by taking 2D 3D-photoluminescence imaging profiles. Various sharp emissions between 580 720 nm assigned the 5 D0 →7 FJ (J = 0, 1, 2, 3, 4) transitions activators. On basis X-ray diffraction crystallography, Auger elemental mapping asymmetry ratio, found be well doped into low (1 mol%) doping level. A broad emission 460 nm substantially increased upon higher (2 mol%) due defect creation. first 3D photoluminescence profiles highlight detailed understanding Al oxide-based phosphor their potential
