New Findings from S. Ren and Co-Authors in the Area of Nanocrystals Reported (Synthesis of white light LaF3: 20%Yb3+, 0.1%Ho3+, 1%Tm3+ single nanocrystals by precipitated transformation method)

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Nanocrystals. According to news reporting out of Hohhot, People's Republic of China, by NewsRx editors, research stated, "In this article, we describe the production of uniform hexagonal phase LaF3:20%Yb3+, 0.1%Ho3+, 1%Tm3+ (LFYHT) monodisperse nanoparticles through a hydrothermal precipitated transformation reaction using La(OH)(3): 20%Yb3+, 0.1%Ho3+, 1%Tm3+ (LOYHT) nanorods as parent materials. The trivalent rare earth hydroxides were hydrothermally prepared at 180 degrees C. Powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) analysis showed the LFYHT nanoparticles to have an average size of 10 nm and diameters similar to those of LOYHT nanorods."

Our news journalists obtained a quote from the research, "The upconversion spectra of the sample were measured using a fluorescence spectro-photomere with single-wavelength diode lasers (980 nm) at room temperature. Red, green, and blue emissions were associated with the synthesized sample."

According to the news editors, the research concluded: "The calculated color coordinates demonstrated that white light can be produced in a wide range of pumping powers."
