摘要

本文报道了固态反应（SSR）合成Ca2La3(SiO4)3F:Dy3+的结构表征和发光研究。它属于空间群\(P{6}_{3}/m\)的六边形体系。SEM和EDAX研究证实了微晶粉末的形成和纯相的形成。该荧光体在573 nm附近表现出由4F9/2→6H13/2电子跃迁引起的强发光峰，在386 nm激发时表现出弱发光峰。黄绿色发射是由CIE色坐标图确认的。因此，这种荧光粉在固态照明、显示设备和其他光学应用中得到了应用。

Structural and spectroscopic properties of Ca2La3(SiO4)3F: Dy3+ phosphor

This article reports the structural characterization and luminescence study of Ca₂La₃(SiO₄)₃F:Dy³⁺ synthesized by solid state reaction (SSR) route. It belongs to hexagonal system with space group \(P{6}_{3}/m\). SEM and EDAX study confirm formation of micro-crystalline powder and pure phase formation. The phosphor exhibits well intense peak around 573 nm attributed to electronic transition ⁴F_9/2 → ⁶H_13/2 along with other weak emission peaks when excited at 386 nm. Yellow-green emission is confirmed by the CIE chromatic coordinate diagram. This phosphor thus finds applications in solid state lighting, display devices and other optical applications.
