CaZrO₃ ceramic pigment exhibits high chemical, thermal and structural stability. However, its application as a host for various luminophores/activators has not been clearly explored. In the present investigation, CaZrO₃ doped with Eu³⁺, as a potential orange-red phosphor has been demonstrated. Ca_1-xZrO₃:Eu_x (x = 0.01–0.09) nanophosphor is prepared here through a low temperature, one pot solution combustion synthesis approach using glycine as the fuel. X-ray diffraction results show that all the samples are stabilized in orthorhombic crystal structure without any impurity phases. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high resolution TEM are carried out to determine the microstructure of the phosphor. The particles are found to be significantly agglomerated and in the nano-regime (∼40 nm). The observed excitation spectrum suggests that Ca_1-xEuZrO₃ can be efficiently excited using ultra-violet (UV), near-UV and UV blue (UVB), making it immediately relevant for current solid state lighting technologies. In fact with every ∼1 at% doping increase, the primary excitation line intensity increases by a factor of ∼1.5; this provides a simple parameter to enhance the UV excitability of the phosphor. The color coordinates are deduced using the Commission International De Eclairage (CIE) co-ordinates (x, y = 0.58, 0.40). The critical distance of energy transfer in this system is determined to be ∼10.7 Å, making multipole-multipole interactions as the plausible reason for concentration quenching beyond 7 mol.% Eu doping. The luminescence behaviour of the material is evaluated using Judd-Offelt (JO) intensity parameters. Judd-Ofelt (JO) intensity parameters (Ω₂ and Ω₄) are calculated for the sample Ca_1-xZrO₃:Eu_x (x = 0.01–0.09), in order to understand the local structure around the activator. Irrespective of the concentration of Eu³⁺, Ω₂ is found to be greater than Ω₄, indicating asymmetric environment around the activator. Furthermore, with increase in Eu³⁺, Ω₂ increases suggesting an increase in covalency of Eu-O bonds with significant effect of host crystal field on Eu³⁺.

CaZrO ₃陶瓷颜料具有很高的化学，热和结构稳定性。然而，尚未明确探索其作为各种发光体/活化剂的宿主的应用。在本研究中，已经证明了掺杂有Eu ^3+的CaZrO ₃作为潜在的橙红色磷光体。Ca _1-x ZrO ₃：Eu _x（x = 0.01-0.09）通过使用甘氨酸作为燃料的低温，一锅溶液燃烧合成方法制备纳米磷光体。X射线衍射结果表明，所有样品均稳定在正交晶体结构中，没有任何杂质相。进行扫描电子显微镜（SEM），透射电子显微镜（TEM）和高分辨率TEM来确定磷光体的微观结构。发现这些颗粒明显团聚并且处于纳米区域（约40 nm）。观察到的激发光谱表明，Ca _1-x EuZrO ₃可以使用紫外线（UV），近紫外线和紫外线蓝（UVB）有效激发光，使其立即与当前的固态照明技术相关。实际上，每增加约1 at％的掺杂量，一次激发线的强度就会增加约1.5倍。这提供了一个简单的参数来增强磷光体的紫外线激发性。使用国际照明委员会（CIE）坐标（x，y = 0.58，0.40）推导出颜色坐标。确定该系统中能量转移的临界距离为〜10.7Å，使得多极-多极相互作用成为浓度猝灭超过7摩尔％Eu掺杂的合理原因。使用Judd-Offelt（JO）强度参数评估材料的发光行为。贾德-Ofelt理论（JO）强度参数（Ω ₂和Ω ₄）被计算为样品的Ca _1-X的ZrO ₃：Eu的_X（X = 0.01-0.09），以了解围绕活化剂的局部结构。不论Eu的浓度的³⁺，Ω ₂被发现是大于Ω ₄，指示周围的活化剂的非对称环境。此外，在增加的Eu ³⁺，Ω ₂的增加表明与基质晶体场的对Eu显著效果的增加的铕-O键的共价性³⁺。
