Curcuminoids, a polyphenol from turmeric (Curcuma longa L.) have well-known diverse medical benefits. However, the nature of emitted light from curcuminoids and their poor stability limit their illumination applications but can be further improved using nanofibers and nanoparticles of curcuminoids. In this study, poly(methyl methacrylate) (PMMA) integrated curcuminoid nanofibers (PICNFs) were prepared through electrospinning and characterised. PMMA was mixed with C. longa L. powder to obtain impurity-free curcuminoid solution. Solutions with altering volumes (1, 2, 3, 4 and 5 ml) were spun to grow desired PICNFs. The structural, morphological and optical properties of the as-synthesised PICNFs (with and without annealing) were evaluated as a function of various PMMA concentrations (5, 10 and 15 wt%) to determine the feasibility of improving down-conversion white light emission. The chromatic traits of the proposed PICNFs were analysed under different light-emitting diode LED pumping wavelengths (365, 390 and 445 nm). The chromaticity coordinates (CIE), correlated colour temperature (CCT) and colour rendering index (CRI) of the obtained PICNFs were measured. The FTIR spectra of as-grown PICNFs displayed various characteristic IR bands, which were assigned to the vibrations of different functional groups in the structures. The FESEM images of pre- and post-annealed samples revealed the formation of nanofibers (diameter ranging from 250 nm to 300 nm) and nanoparticles (diameter ranging from 9 nm to 18 nm). The optimum values of CIE, CRI and CCT for the studied PICNFs were (0.3092, 0.315), 76.3 and 6,856 K, respectively.

姜黄素是姜黄（Curcuma longa L.）的多酚，具有众所周知的多种医学益处。但是，姜黄素类化合物发出的光的性质及其较差的稳定性限制了它们的照明应用，但可以使用纳米纤维和姜黄素类化合物的纳米颗粒进一步加以改善。在这项研究中，聚（甲基丙烯酸甲酯）（PMMA）集成姜黄素类纳米纤维（PICNFs）通过电纺丝制备并进行了表征。将PMMA与长果梭状芽孢杆菌粉末混合以获得无杂质的姜黄素溶液。与改变体积解决方案（1，2，3，4至5米升将其旋转以生长所需的PICNF。根据各种PMMA浓度（5、10和15 wt％）对合成后的PICNF（具有和不具有退火）的结构，形态和光学性质进行了评估，以确定改善下转换白光发射的可行性。在不同的发光二极管LED泵浦波长（365、390和445 nm）下分析了所提出PICNF的色度特性。测量获得的PICNF的色度坐标（CIE），相关色温（CCT）和显色指数（CRI）。生长中的PICNF的FTIR光谱显示出各种特征性IR波段，这些波段被分配给结构中不同功能组的振动。退火前和退火后样品的FESEM图像显示了纳米纤维（直径范围为250 nm至300 nm）和纳米颗粒（直径范围为9 nm至18 nm）的形成。对于所研究的PICNF，CIE，CRI和CCT的最佳值分别为（0.3092、0.315），76.3和6,856K。
