摘要

在单一宿主中具有单一激活剂的白光发射是荧光粉的一种有吸引力的功能。本文研究了Ba5(PO4)3-x(BO3)xCl的光致发光性质。Ba5(PO4)3-x是一种由磷灰石型Ba5(PO4)3Cl通过二偶代取代得到的化合物，通过Eu2+活化进行了光致发光测量。在近紫外光激发下，荧光粉显示出从深蓝色到白色再到橙色的可调发射。在化合物Ba5(PO4)3Cl中，Ba2+离子占据两个不同的晶体位置；只有一个位点是Eu2+取代的优先位点。通过在主晶格中引入（BO3）3−基团，观察到附加的发射峰。衰变分析表明，第二次发射是由（BO3）3−基团的引入引起的Eu2+在另一个晶体位置产生的。用Ba4.96(PO4)2.6(BO3)0.4Cl:0.04Eu2+荧光粉和365 nm近紫外芯片成功制备了一种光能转换发光二极管，其色坐标为（0.3151,0.3695），相关色温为6173 K。这些发现为在单一组分中掺杂单一激活剂制备白光荧光粉提供了新的途径。

Single-phase white-emitting phosphors based on Eu2+-activated apatite-type Ba5(PO4)3Cl induced by (BO3)3− diadochic substitution

White-light emission with a single activator in a single host is an attractive function of phosphors. In this work, we investigated the photoluminescence properties of Ba₅(PO₄)_3-x(BO₃)_xCl, which is a compound derived from apatite type Ba₅(PO₄)₃Cl by means of diadochic substitution, with Eu²⁺-activation using photoluminescence measurements. Phosphors show a tunable emission from deep blue to white and then orange under near ultraviolet light excitation. In the compound Ba₅(PO₄)₃Cl, Ba²⁺ ions occupy two crystallographically distinct sites; only one site is preferential site for Eu²⁺ substitution. Through introducing (BO₃)³⁻ group into the host lattice, additional emission peak is observed. Decay analysis indicates that the second emission is generated by Eu²⁺ at another crystallographic site caused by the introducing of (BO₃)³⁻ group. A phosphor-converted light-emitting diode has been successfully fabricated with the incorporation of an as-prepared Ba_4.96(PO₄)_2.6(BO₃)_0.4Cl:0.04Eu²⁺ phosphor and a 365 nm near-ultraviolet chip, which exhibits Commission International de I'Eclairage chromaticity coordinates of (0.3151, 0.3695) and a correlated color temperature of 6173 K. These findings provided a new way for preparing white light phosphors by doping a single activator in a single component.
