Abstract:
The BaMoO4:Eu3+ phosphors were synthesized by solid-state method and were characterized by X-ray diffraction (XRD) and photoluminescence spectra. XRD analysis confirmed the formation of BaMoO4 at 800 degrees C and exhibited a tetragonal crystal structure. The excitation spectrum of samples showed one broad band and some peaks located behind 350 nm. The former was attributed to the charge transfer transition of Eu3+-O(2-), while the latter belonged to the f-f transitions of Eu3+ ions. The emission spectrum shows four peaks at 591, 615, 654 and 702 nm, respectively. The dominant peak is located at 615 nm due to the 5D0-7F2 electric dipole transition of Eu3+.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
