Illumination is one of the most important elements of any room or workspace; it is defined as the deliberate use of light to achieve practical or aesthetic effects. The latter, has inspired the design of complex lighting systems such as fibre optic Christmas trees or photoluminescent optical fibres with lateral emission in which the light color is a combination of the light source and the photoluminescence of the active material. Since the intended use of most of these complex lighting systems are mainly decorative, there is a lack of information regarding its performance or manufacturing process. The complex lighting systems proposed is formed by a poly (methyl methacrylate) (PMMA) rod covered by a polymer thin film that contains luminescent nanoparticles. A spray process was used to deposit the thin film with different luminescent particles concentration. The structure, morphology and optical properties of the samples were measured by X-ray diffraction, atomic force microscopy, UV-VIS and photoluminescence spectroscopy, respectively. Results showed that polymer based composite luminescent material could be a good candidate for the development of complex lighting systems.

照明是任何房间或工作空间中最重要的元素之一；它被定义为故意使用光以达到实用或美学效果。后者激发了复杂照明系统的设计，例如具有侧向发射的光纤圣诞树或光致发光光纤，其中光的颜色是光源和活性材料的光致发光的组合。由于大多数这些复杂照明系统的预期用途主要是装饰性的，因此缺乏有关其性能或制造过程的信息。提出的复杂照明系统由聚甲基丙烯酸甲酯（PMMA）棒形成，该棒被包含发光纳米粒子的聚合物薄膜覆盖。使用喷涂工艺沉积具有不同发光颗粒浓度的薄膜。分别通过X射线衍射，原子力显微镜，UV-VIS和光致发光光谱法测量样品的结构，形态和光学性质。结果表明，基于聚合物的复合发光材料可能是开发复杂照明系统的良好选择。
