Researchers from South China University of Technology Report on Findings in Nanocrystals (Enhanced up-conversion in Er3+-doped transparent glass-ceramics containing NaYbF4 nanocrystals)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanocrystals. According to news reporting from Guangdong, People's Republic of China, by NewsRx journalists, research stated, "Highly transparent Er3+ doped oxyfluoride glass-ceramics containing cubic NaYbF4 nanocrystals were fabricated in an aluminosilicate matrix by melt-quenching technique. Their structural properties, optical properties and enhanced up-conversion behaviors were systemically investigated by XRD, TEM, HRTEM techniques and absorption, up-conversion spectra."

The news correspondents obtained a quote from the research from the South China University of Technology, "Excited by 980 nm laser, samples present characteristic emissions of Er3+. Compared with precursor glasses, the intensity of red emission increases by 15 times for GC650 after crystallization."

According to the news reporters, the research concluded: "Our work indicates that transparent NaYbF4 glass-ceramics may be used as potential host for up-conversion."
