Abstract
- A series of La (3- x) Dy x BWO 9 phosphors and La (3- x) Dy x BWO 9 /PMMA composite films were prepared. The absorption and photoluminescence of phosphors as well as the transmittance and radioluminescence of the composite films were studied. La (3- x) Dy x BWO 9 phosphors mainly emit blue light at 486 nm and yellow light at 577 nm when excited at 310 nm, and the phosphors have good thermal stability. La (3- x) Dy x BWO 9 /PMMA composite films have good transmittance and X-ray radiation properties. The results indicate that La (3- x) Dy x BWO 9 phosphors can be used in solid-state lighting devices, and the prepared composite films are expected to be used in fields such as X-ray imaging and radiation detection.
