As part of the inspection of the substrate, a photoluminescent material may be applied to the part of the substrate. The photoluminescent material comprises a conjugated polymer having a coiled macromolecule shape and a meta-or ortho-bond. The substrate is imaged using an inspection system. The conjugated polymer may be, for example, poly (m-phenylene [stretch] acetylene) (PPE) or poly (p-phenylethylene) (PPV). 作为衬底检验的部分，可将光致发光材料施加到衬底的部分。所述光致发光材料包含具有盘绕宏观分子形状及间键或邻键的共轭聚合物。使用检验系统来使所述衬底成像。所述共轭聚合物可为(例如)聚(间伸苯[伸]乙炔)(PPE)或聚(对位苯基乙烯)(PPV)。
