Abstract

Blue-green dual-emitting phosphors Ca 3 Lu(GaO) 3 (BO 3 ) 4

A broadband cyan-emitting Ca2LuZr2(AlO4)3:Ce3+ garnet phosphor for near-ultraviolet-pumped warm-white light-emitting diodes with an improved color rendering index

“…When monitored at 483 nm, the resulting PLE spectrum contained two excitation band peaks at 348 nm (in the 300-370 nm range) and 408 nm (in the 370-475 nm range), which were attributed to the 4f -5d transitions of Ce 3+ ions. [46][47][48] Obviously, the excitation band in the 370-475 nm range dominated the PLE spectrum of the CLZA:1% Ce 3+ phosphors, and the excitation band in the 370-475 nm range was asymmetric and consisted of two Gaussian sub-bands with the peaks at around 393 and 411 nm. Under the excitation of 408 nm, the PL spectrum of the CLZA:1% Ce 3+ phosphors was recorded.…”

Insight into luminescent properties, energy transfer and thermal stability of NaBa4(AlB4O9)2Cl3:Ce3+, Tb3+ phosphors

“…Sun and Xia reported on their investigations together on the energy transfer process in BaAl 2 B 2 O 7 :Ce 3+ , Tb 3+ phosphors, with the transferring efficiency calculated to be 71% due to a dipole‐dipole interaction mechanism. Huang et al synthesized Ca 3 Lu(GaO) 3 (BO 3 ) 4 :Ce 3+ , Tb 3+ phosphors and adjusted the emission color from blue to green to fabricate a prototype w‐LED device. Wang et al prepared polyaspartate coated LaF 3 :Ce 3+ /Tb 3+ luminescent nanocrystals utilize the energy transfer process within to sense iron ions.…”

Synthesis and photoluminescence properties of novel far-red-emitting BaLaMgNbO6:Mn4+ phosphors for plant growth LEDs

“…7,8 Compared to traditional incandescent and uorescent lamps, light emitting diodes (LEDs) have become the promising candidates for articial light sources for plant growth due to their extraordinary advantages such as the high luminescence efficiency, energy saving, and good stability. [9][10][11][12][13][14][15][16][17][18] Especially, LEDs can adjust the spectral composition by using various phosphors to match with the spectrum of plant photosynthesis and photomorphogenesis. So, nowadays LEDs have been widely applied in indoor plant growth.…”
