This review summarizes recent work in nanostructured insulating materials that contain
optically active lanthanide ions. These materials find applications in lasers, optical …

Yttrium oxide (Y2O3) thin films were grown onto Si (100) substrates using reactive
magnetron sputter-deposition at temperatures ranging from room temperature (RT) to 500° …

Due to the “efficiency droop” effect of light-emitting diodes (LEDs) under high drive currents,
laser diode (LD) driven light sources are considered to replace LED lighting for the next …

Rare-earth ion (Eu3+, Tb3+, Ce3+)-doped LaPO4 nanocrystalline thin films and their
patterning were fabricated by a Pechini sol–gel process combined with soft lithography on …

Thin films of yttrium oxide doped separately with Eu3+, Tb3+ and Tm3+ were deposited by
spray pyrolysis. The effect of preparation conditions on the structural and …

Thin films of Zn2SiO4: Tb3+ or Eu3+ were deposited on silicon wafers by a sol–gel method.
The films exhibited prominent green or red photoluminescence, due to the sharp and strong …

Recent advances in the phosphors used for field emission displays (FEDs) are discussed.
After reviewing the range of voltages and phosphors being used in first generation devices …

Eu-, Tb-, and Tm-doped zinc aluminate (ZnAl2O4) thin film phosphors were prepared by the
spray pyrolysis technique at an ambient pressure. The effects of preparation conditions on …

Pure and rare earth doped gadolinium oxide (Gd2O3) waveguide films were prepared by a
simple sol–gel process and dip-coating method. Gd2O3 was successfully synthesized by …

The particle size of conventional commercial phosphor powders used in lighting and
displays is in the range from several micrometers to tens of micrometers and it is known that …
