Synthesis And Luminescence Properties Of Camoo4:Sm3+ Phosphors For Orange Photonic Materials, N Luewarasirikul, J Kaewkhao, H Kim

Journal of Metals, Materials and Minerals

The series of CaMoO4 samples with different melting temperature (600, 700, 800 and 900°C) were synthesized in this work to investigate their phase structures by X-ray diffraction (XRD). The XRD result confirmed that the crystalline structures of the phosphors were obtained at 800°C (tetragonal structure with I41/a space group). Then, the series of Ca1-xMoO4:Smx (where x = 0.005, 0.010, 0.015, 0.020, 0.025 and 0.030) were prepared by solid-state reaction method to study their luminescence properties. The absorption spectra, recorded in UV, Vis and NIR regions, showed peaks at 405, 465, 952, 1096, 1252, 1405, 1513, 1573 and 1629 nm. The …
