“…Compared with conventional illumination equipment, white light-emitting diodes (WLEDs) have several advantages such as high luminous efficiency, low power consumption, maintenance and environmental protection [1][2][3]. There are two methods for fabricating WLEDs (blue chip + yellow phosphor and near-ultraviolet (NUV) chip + tricolor (red, green, and blue) phosphors).…”

A series of Sm 3? , Eu 3? and Sm 3? -Eu 3? doped Ca 3 (PO 4 ) 2 were prepared by a high temperature solid-state method. Their luminescent properties were studied by photoluminescence emission, excitation spectra and decay curves. Under excitation with a wavelength at 403 nm, Ca 3 (PO 4 ) 2 :Sm 3? emits red-orange light, and the dominated peak situates at 602 nm which is due to the 4 G 5/2 ? 6 H 7/2 transition of Sm 3? . Ca 3 (PO 4 ) 2 :Eu 3? produces red light under the 394 nm excitation, and the strongest peak centers at 613 nm, which is assigned to 5 D 0 ? 7 F 2 transition of Eu 3? . The energy transfer from Sm 3? to Eu 3? in Ca 3 (PO 4 ) 2 host has been studied and demonstrated to be a resonant type via a dipole-quadrupole interaction mechanism. The critical distance of Sm 3? -Eu 3? in Ca 3 (PO 4 ) 2 is calculated to be 13.5 Å . With the increase of Eu 3? doping content, the energy transfer efficiency (Sm 3? ? Eu 3? ) obtained from decay curves gradually increases to 30.7 %. Moreover, the emitting color of Ca 3 (PO 4 ) 2 :Sm 3? , Eu 3? can be tuned by appropriately adjusting the relative doping composition of Sm 3? /Eu 3? .

“…The rare‐earth ions Sm 3+ are often used as activators of orange‐red phosphors . However, the luminescence properties of Sm 3+ ‐doped phosphors have some shortcomings because the Sm 3+ luminescence belongs to the inter‐level transition, such as weak luminescence intensity and narrow excitation range (about 10 nm at half‐width), which limit the application of phosphors to a large extent . Therefore, it is an urgent task to broaden the excitation of Sm 3+ doped phosphors.…”

A novel tunable red emitting phosphor LiBaB O :Sm /Sm , Li with broad excitation band was synthesized by a high temperature solid-state method. Luminescence properties were investigated in detail by luminescence, X-ray photoelectron spectroscopy (XPS) spectra and CIE chromaticity coordinates. XPS data confirmed that there were Sm in LiBaB O :Sm and Sm /Sm in LiBaB O :Sm /Sm , respectively. Spectral property of LiBaB O :Sm , LiBaB O :Sm /Sm and LiBaB O :Sm , Li presented that the excitation band of Sm widened and the excitation band of Sm ranged from 350 to 450 nm. And the red light color is tunable with changing Li concentration. The results indicated that LiBaB O :Sm /Sm , Li may be promising red phosphor for white light emitting diodes.
