The Red-Emitting Phosphor of Sm³⁺-Doped Y₂Si₄N₆C

Abstract:

A new red-emitting Rare-earth silicon carbonitrides phosphor, Y₂Si₄N₆C, was prepared by a carbothermal reduction and nitridation method. X-ray powder diffraction (XRD), the photoluminescence excitation and emission spectra, temperature dependent was measured. The emission spectrum obtained by excitation into 410 nm contains exclusively the characteristic emission of Sm3+ at 568, 607 and 654 nm which correspond to the transitions from ⁴G_5/2 to ⁶H_5/2, ⁶H_7/2, and ⁶H_9/2 of Sm³⁺, respectively. The strongest one is located at 606 nm due to ⁴G_5/2 to ⁶H_7/2 transition of Sm³⁺ .
