题目:Inorganic Luminescent Materials: Design, Synthesis, Properties and Applications
简介:As for the long persistent luminescence, the past two decades have witnessed the significant achievements on the visible and near infrared (NIR) persistent phosphors, while the research and development of persistent phosphors in the ultraviolet (UV) spectral region (200–400 nm) and short-wave infrared (SWIR) region (900–1700 nm) are lacking due to the limit of suitable host materials and emitters. On the other hand, the fluoride-based upconversion luminescent materials have deficiencies including poor chemical stability, high cost, and harsh preparation condition, which limit to some extent their wide applications. In consequence, there is still a strong demand ongoing for developing new host materials, espically the oxide hosts with good chemical stability.
In this report, I will first introduce the current situation and development of persistent luminescence materials and upconversion luminescent nanomaterials. Then I will focus on the development and application of novel germanate-based persistent phosphors. Next, the preparation and luminescence properties of upconversion luminescent nanomaterials will be discussed. At last, I will give a short introduction about Bi-based nanomaterials for catalysis and bioimaging applications.
