Oxvfluoride glass ceramic doped with doped with Er^(3+)/Yb^(3+)was synthesized.Rare earth ions are doped into fluoride nanocrystals according to x-ray diffractive patterns.The enhanced red emission of Er^(3+)/Yb^(3+)i...
An anti-reflective (AR) fluoride coating in the 170-230 nm spectral range is prepared by the thermal evaporation method for the applications of widely tunable deep-ultraviolet diode-pumped solid-state lasers. The tr...
Different fluoride materlals are used as gate dielectrics to fabricate copper phthalocyanine (CuPc) thin film transistors (OTFTs). The fabricated devices exhibit good electrical characteristics and the mobility is...
