高温固相反应光致发光热稳定性 Sr3ZnNb2O9∶0.3Eu3+, xNa+ Sr3ZnNb2O9∶0.3Eu3+, xNa+ high temperature solid-state reaction photoluminescence thermal stability

摘要

本文通过高温固相反应成功制备了Sr3ZnNb2O9∶0.3Eu3+, xNa+(x=0,0.1,0.2,0.3,0.4,0.5)系列荧光粉。X射线衍射分析和精修结果表明，Eu3+和Na+成功掺杂到Sr3ZnNb2O9基质中，并部分取代了Zn2+。采用扫描电子显微镜测试了样品的微观形貌和元素分布。光谱特性和热稳定性研究表明，Na+的最佳掺杂浓度为x=0.2，Na+的引入提高了Sr3ZnNb2O9∶0.3Eu3+荧光粉的热稳定性，活化能为0.163 eV。计算出Sr3ZnNb2O9∶0.3Eu3+, 0.2Na+样品的CIE色坐标为(0.618, 0.376)，相关色温和色纯度分别为1 855 K和98.46%。

Abstract

In this paper, Sr3ZnNb2O9∶0.3Eu3+, xNa+ (x=0,0.1,0.2,0.3,0.4,0.5) phosphors were successfully prepared by high temperature solid-state reaction. XRD patterns and refinement results show that Eu3+ and Na+ are successfully doped into the matrix and partially substituted Zn2+. The microscopic morphology and element distribution of the samples were confirmed by scanning electron microscopy. The spectral characteristics and thermal stability analysis show that the optimal doping concentration of Na+ is x=0.2. The introduction of Na+ improves the thermal stability of Sr3ZnNb2O9∶0.3Eu3+ phosphors and the calculated activation energy is 0.163 eV. The CIE color coordinate of the Sr3ZnNb2O9∶0.3Eu3+, 0.2Na+ samples is calculated to be (0.618, 0.376), the correlated color temperature and the color purity are 1 855 K and 98.46%, respectively.
