Cathodoluminescence (CL) properties of SiO2 powders activated with thulium
(Tm3+) and holmium (Ho3+) ions prepared by a sol–gel process were
investigated. Different molar concentrations of Tm3+ co-doped with Ho3+ were
studied. The 460 nm peak was monitored and the influence of the beam
energy and concentration of Tm3+ ions on the emission properties of this peak
was also monitored. The peculiar behavior whereby the 460 nm emission peak
decreases and the increase in the 705 and 865 nm peaks with the increase in
the concentration of Tm3+ ions is reported. The relationship between the
accelerating beam voltage and the CL intensity of the blue emission peak (460
nm peak) is established. Morphology, particle size and optical properties were
characterized with Scanning electron microscopy (SEM), UV/VIS Lambda 750 S
spectrometer and Auger electron spectroscopy (AES) equipped with Ocean
Optics S2000, respectively. |
