摘要:

稳定可靠的高光子能量发光(620~650 nm)红光荧光粉, 对于构建低色温、高显指荧光粉转换型白光发光二极管(WLED)至关重要。Mn 4+激活红光荧光粉是当前WLED用荧光粉研究热点之一。本文介绍了Mn 4+离子的能级跃迁与光致发光特性, 详细叙述了目前所报道的七种Mn 4+激活含d 0/d 10/s 0离子氧氟化物系列红色荧光粉(如Na2WO2F4:Mn 4+等)的制备方法、晶体结构及其发光特性。目前Mn 4+在氧氟化物结构中得到强R线发光的情况少, 微观配位体仍是[MnF6]或[MnO6], 其化学稳定性和量子效率研究也很缺乏。最后对Mn 4+激活氧氟化物红光荧光粉的研究进行了展望。

Abstract:

The stable and reliable red phosphor with high-photon energy emission (620-650 nm) is critical for the fabrication of the phosphor-converted white light-emitting diode (WLED) with low correlated color temperature and high color rendering index. Mn 4+-activated phosphor is an emerging kind of red-emitting phosphor for WLED. Herein, the energy levels transition and photoluminescence characteristics of the Mn 4+ ion were introduced; then, the preparation, crystal structure and luminescent properties of as-far reported seven kinds of Mn 4+-doped oxyfluoride red phosphors (such as Na2WO2F4:Mn 4+) containing d 0, d 10 or s 0 cations were reviewed. Currently, only in quite rare case of oxyfluoride, Mn 4+ was found to exhibit strong R-line emission, with local coordination remaining as either [MnF6] or [MnO6]. The studies on the chemical stability and quantum efficiency of Mn 4+-doped oxyfluoride phosphors are still insufficient. Finally, we prospected the future development of Mn 4+-doped oxyfluoride phosphor.
