“…It can be observed that the excitation spectrum monitored at 360 nm contains a broad and strong band extending from 200 to 350 nm, attributed to the 4f-5d transition of Ce 3? [15]. Under excitation by 290 nm, the emission spectrum of Ca 3 (PO 4 ) 2 :0.04Ce 3? presents an asymmetric band that ranges from 320 to 440 nm with a maximum at 360 nm, which is derived from the 5d-4f transition of Ce 3?…”

A series of Ce 3? , Tb 3? and Ce 3? -Tb 3? -doped Ca 3 (PO 4 ) 2 were prepared by high-temperature solid-state reaction, and X-ray diffraction was used to characterize the phase structure. The photoluminescence and energy transfer properties of Ce 3? -and Tb 3? -doped Ca 3 (PO 4 ) 2 host were investigated. Under the 290-nm radiation excitation, the emission spectrum of Ca 3 (PO 4 ) 2 :Ce 3? shows one broad band that peaks at 360 nm, which is attributed to the 5d-4f transition of Ce 3? . Ce 3? and Tb 3? co-doped Ca 3 (PO 4 ) 2 phosphors exhibit both blue emission from Ce 3? ions and intense green emission lines from Tb 3? at the excitation of Ce 3? . These results indicate that there exits valid energy transfer from Ce 3? to Tb 3? . The energy transfer from Ce 3? to Tb 3? in Ca 3 (PO 4 ) 2 was demonstrated to be a resonant type via electric dipole-quadrupole interaction. The critical distance of energy transfer was also calculated. Moreover, the emitting color of Ca 3 (PO 4 ) 2 :Ce 3? , Tb 3? can be tuned by appropriately adjusting the relative doping composition of Ce 3? /Tb 3? .

“…For the aluminate and phosphate compounds, such as ZnAl 2 O 4 , CaYAl 3 O 7 , Sr 2 P 2 O 7 , Sr 3 Gd(PO 4 ) 3 and KSrY(PO 4 ) 2 , the available energy transfer between Ce 3? and Tb 3? also diffusely exists [6,[12][13][14][15]. The most famous representative ones are phosphors LaPO 4 :Ce 3?…”

“…However, the narrow line width and the low oscillator strength of the parity-forbidden 4f → 4f absorption transitions of RE cations result in a weak absorptivity in the ultraviolet (UV) range [1,4,7,8]. As a result, RE cations with the small absorption cross section cannot be efficiently pumped by UV excitation sources [1,9,10].…”

“…For example, in the pure white Na 3 Gd(PO 4 ) 2 :Dy,Tm phosphor, the Tm 3+ ion acts as a sensitizer and enhance the Dy 3+ emission [9]. An efficient energy transfer from Ce 3+ to Tb 3+ , with an energy transfer efficiency ( ET η ) of 68.3% and a wide color tunable range from deep blue to green, was obtained using the KSrY(PO 4 ) 2 :Ce,Tb phosphor [5]. Additionally, in the [11].…”

“…However, not all luminescence centers/activators have the required energy absorption efficiency. The energy absorption and luminescence of activators can be significantly increased using the Förster and Dexter energy transfer mechanisms [4][5][6][7][8]. For example, in the pure white Na 3 Gd(PO 4 ) 2 :Dy,Tm phosphor, the Tm 3+ ion acts as a sensitizer and enhance the Dy 3+ emission [9].…”
