Abstract
In this work, the glazed ceramic doped with Ho3+ ions were introduced to understand luminescence artwork. The glaze samples were seperated to three conditions consist of raw glaze material (GR), glaze mixing with Ho2O3 before melting (GHo), and glaze mixing with Ho2O3 after melting (GHoM). The samples were analyzed by X-ray fluorescence (XRF), X-ray diffractometry (XRD), scanning electron microscopy (SEM), optical and luminescence spectral properties. The absorption spectra in the visible and near-infrared region were being identified at 361, 419, 453, 486, 539, 646, 900, 1,157, and 1,963 nm. For luminescence spectra, the result showed a strong emission peak at 543 nm via 5F4-5I8 transition of Ho3+ under excitation at 398 nm. Moreover, the SEM images revealed homogeneous dispersion of glazed sample with Ho3+ ions. The glazed ceramic containing Ho3+ ions can be considered as luminescence artwork for ceramic materials.
