Improving NTSC to Achieve Near-RGB Performance

Structure and photoluminescence characteristics of europium(iii) doped in CaAl2Si2O8phosphors

“…The CIE chromaticity coordinates of optimized concentration are shown by point 3 (0.59, 0.28), which is the NTSC system standard for red chromaticity. 39,40 It is clear that this series of phosphors exhibits excellent CIE coordinates, which are sited in the reddish colour area. There are two key factors that are considered to be the reason for controlling the position of the C 1À3x/2 ASO:xEu 3+ phosphors in the CIE diagram: (i) the asymmetric ratio increases with increasing Eu 3+ concentration in the host lattice; and (ii) the varied intensities of the emission band following the dopant concentrations.…”
