Yb^3+:Er^3+:Tm^3+co-doped borosilicate glasses are prepared. Their strong up-conversion photoluminescence spectra in a range from ultra-violet to near-infrared, which are excited by a 978-nm laser diode, are meas...
To investigate the upconversion emission, this paper synthesizes Tm^3+ and Yb^3+ codoped Y2O3 nanoparticles, and then coats them with TiO2 shells for different coating times. The spectral results of TiO2 coated nano...
