Luminescence Properties of Eu2+ Doped β-SiAION Phosphor
Eu2+doped p-SiAlON (z=1,3,4) phosphor were synthesized by carbothermal reduction-nitridation (CRN) using precursors powder as materials. The precursors powder prepared by sol-gel method using the SiO2,AlCl3·6H2O,Eu(NO3)3 ammonia water, carbon powders as starting materials. The CRN reaction proceeded at 1380℃ for 6 h in an N2 atmosphere. Eu2+doped P-SiAlON (z=1,3, 4) had high adsorption in the UV-visible spectral region. While z=1, one bands were observed in the emission spectrum centered at about 425 nm monitored at 282 nm. The excitation bands centered at about 282 nm. While z=3, one bands were observed in the emission spectrum centered at about 425 nm monitored at 282 nm. The excitation bands centered at about 282 nm. While z=3, the emission spectra exhibit one bands with maxima at about 419 nm under 280 nm excitation. The excitation bands centered at about 280 nm. While z=4, the emission spectrum centered at about 419 nm monitored at 280 nm. The excitation bands centered at about 280 nm. Hi this work, luminescence properties of Eu2+doped p-SiAlON (z=1,3,4) are independent of z value. It is possible related to the low synthesis temperature.
