Outline of Final Research Achievements

Particle size and dopants were optimized to obtain higher quantum efficiency in Er3+ doped fluoride nanocrystals. Doping of other lanthanide ions, except Yb3+, did not enhance quantum efficiency in the Er3+ doped nanocrystals. Transparent polymer composites containing nanocrystals were prepared. The scattering loss caused by the embedded nanocrystals were reduced. Optical waveguides based on the composite materials were successfully fabricated using laser-induced self-written technique. Amplified spontaneous emission was observed. Two optical waveguides based on the composite polymer were fabricated with X-type structure. This technique of fabricating nanocrystals doped novel waveguides could be promising for developing novel optical devices in the future.
