Abstract
AbstractA facile method to synthesis of CaWO4:Ln3+ nanocrystals and transparent CaWO4:Ln3+/polystyrene (PS) or polymethyl methacrylate (PMMA) copolymer films with outstanding luminescent property and high transparency is proposed. The average diameter of CaWO4:Ln3+ nanorods is 3.3 ± 3 nm, and the average length is 40.3 ± 20 nm. The as‐prepared CaWO4:Ln3+/PS or PMMA copolymer films with high solids loading (>5 vol%) exhibit excellent near‐ultraviolet absorption and outstanding visible transparency under the naked eye. The experiment results about the relationship between the solids loading and the film transparency are compared and analyzed. These optical results suggest that our nanorod has a versatile strategy for producing highly transparent functional luminescent composites, which indicates the promising applications in the field of optoelectronics in the future.
