Near UV excited highly pure red light emitting Ca₃B₂O₆:Eu³⁺phosphor was synthesized via a solution combustion method. The prepared samples were examined using Powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS) and Photoluminescence (PL) spectroscopy for their structural, spectral, surface, and luminescent studies. The XRD and FTIR results showed the formation of a single phase Ca₃B₂O₆ compound with BO₃ and BO₄ structural units. PL emission spectra under near UV excitation show characteristic emission for the Eu³⁺ ion (⁵D₀→⁷F_j, j= 0, 1, 2, 3 and 4) with the main red emission peak at 614 nm corresponding to the ⁵D₀→⁷F₂ transition state of the Eu³⁺ ion. The XPS results depicted that all the elements were presented on the surface of the material and the Eu ion was presented in the (+3) state. The density of states and bandgap of the material was approximated by employing the density functional theory. Moreover, the decay time, International Commission on Illumination coordinates, and color purity were also calculated and reveals that the phosphor can be a potential material as a red component for white light emitting diodes (wLED). Phosphor with short decay time, Commission International del’Eclairage (CIE) coordinated seen to the strong red emission and high color purity reveal that the phosphor can be a potential material as a red component for white light emitting diodes (wLED).

通过溶液燃烧法合成了近紫外线激发的高纯红色发光Ca ₃ B ₂ O ₆：Eu ³⁺荧光粉。使用粉末X射线衍射（XRD），傅立叶变换红外（FT-IR），X射线光电子能谱（XPS）和光致发光（PL）光谱对制备的样品进行结构，光谱，表面和发光研究。XRD和FTIR结果表明形成具有BO ₃和BO ₄结构单元的单相Ca ₃ B ₂ O ₆化合物。近紫外激发下的PL发射光谱显示Eu ³⁺离子的特征发射（⁵ D ₀ → ⁷ F _j，j = 0、1、2、3和4），主要的红色发射峰在614  nm处对应于Eu ³⁺的⁵ D ₀ → ⁷ F ₂过渡态离子。XPS结果表明，所有元素均存在于材料表面，而Eu离子以（+3）态存在。材料的状态密度和带隙密度是通过使用密度泛函理论来估算的。此外，还计算了衰减时间，国际照明委员会坐标和色纯度，并揭示了磷光体可能是潜在的材料，可作为白色发光二极管（wLED）的红色成分。具有短衰减时间的磷光体，国际照明委员会（CIE）协调观察到强红色发射和高色纯度表明，磷光体作为白光发光二极管（wLED）的红色组分可以作为潜在的材料。
