Fabrication of high-efficiency YAG:Ce3+ phosphors via concurrent optimization of firing atmosphere and fluxing agent

Polarization-dependent photoluminescence of Ce-implanted MgO and MgAl2O4

“…The calculation of the spin coherence based on the CCE, which ignores the effect of T 1 , predicts that T 2 of MgAl 2 O 4 is in the order of 0.1 ms. 28) T emi of Ce in the oxides is typically in the order of about 60 ns. 42) Thus, the magnetic field and temperature dependences of the polarization-dependent optical properties of Ce-implanted MgAl 2 O 4 suggest that the spin-dependent emission is hindered by the short T 2 limited by…”

First-Principles Analysis of the Effects of Covalency and Ionicity on the 4f–5d Transition Energy of Ce3+ in Garnet-Type Oxides

“…A well-known wLED is based on the combination of Ce 3+ -doped Y 3 Al 5 O 12 [yttrium aluminum garnet (YAG)] phosphor with blue InGaN chip. [18][19][20][21][22] Phosphors based on various oxide hosts are important as luminescent materials to convert high-energy blue or ultraviolet (UV) light for wLEDs. The rare earth (RE) elements such as Ce 3+ (4f 1 ) or Eu 2+ (4f 7 ) are widely employed as a luminescent center because the crystal field strength of the 5d-4f energy level can be customized and it is usually in the range of visible light emission wavelengths.…”
