摘要：
This work presents the first experimental results of optically stimulated luminescence in organic crystals type enaminones. Samples were synthesized by means of the condensation reaction of acetylacetone with four aromatics amines in acid medium. Component reactions were dissolved and heated in refluxing toluene under magnetic stirring during 14 h. Optically stimulated luminescence has been used in order to explore luminescent emission on organic solids. Optically stimulated luminescence characteristics were obtained using an automatic Lexsygsmart TL/OSL Luminescence reader. Organic crystals type enaminones exhibit good sensitivity to beta radiation. Organic crystals showed OSL response in exponential decay form. The OSL signal was increased as radiation dose was increased. Optically stimulated luminescence in organic crystals type enaminones has been reported at the first time.
