Paper Title:
Luminescence Properties of Eu2+ Doped β-SiAlON Phosphor
  Abstract

Eu2+ doped b-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°C for 6 h in an N2 atmosphere. Eu2+ doped b-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. In this work, luminescence properties of Eu2+ doped b-SiAlON (z = 1, 3, 4) are independent of z value. It is possible related to the low synthesis temperature.
