White Light Emitting Diodes

Novel single-phase Ca2-xBO3Cl:xDy3+ phosphors were synthesized at 900 oC in an activated carbon reducing atmosphere, and their luminescent properties were investigated by photoluminescence (PL) and photoluminescence excitation (PLE) spectra. The optimal doping concentration of Dy3+ ions is found to be x=0.03 mol, and the nature of resonance energy transfer for Dy3+ ions is also discussed. Generation of white-light excited by 390 near-ultraviolet (n-UV) light shows that all the investigated phosphors lie within white region and the colour coordinate of Ca1.95BO3Cl:0.05Dy3+ (0.272, 0.326) is closer to the equal-energy white light point, which is potentially a good candidate as an n-UV-converted phosphor for white light-emitting diodes (LEDs).
