Laser precipitation of Eu and Yb codoped CaF2 nanocrystals on the surface of glass and emission characteristics

Kim D.S., Bae C-H, Lim K-S, Chungbuk National University, KR

We precipitated spatially selective Eu/Yb doped CaF2 nanocrystals on the surface of glass by CO2 laser irradiation. Because of low phonon energy of CaF2, we observed several times enhancements in down-shift emission under 365 nm [...]

Infrared laser precipitation of ZnAl2O4 nanocrystals doped with Eu3+ and Yb3+ ions and efficient upconversion emission

Bae C-H, Lim K-S, Chungbuk National University, KR

We present a novel and simple method to enable spatially selective ZnAl2O4 nanocrystal formation on the surface of glass. Zinc Aluminate, well-known as a wide band gap semiconductor, has been widely used as high temperature [...]
