Long aliphatic chain coated rare-earth nanocrystal as polymer-based optical waveguide amplifiers

Oleic acid-coated erbium–ytterbium co-doped NaYF4 nanocrystals, NaY78%F4 : Yb20%Er2%, have been synthesized. The cubic nanocrystals were of an average size of 10 nm. The nanocrystals showed excellent redispersibility in common organic solvents and the KMBR® polymer matrix. An optical waveguide amplifier was fabricated by doping 0.1 wt% of the nanocrytals into the KMPR® polymeric host. At a small input signal power of 150 nW and a pump power of 150 mW, an optical gain of 4.81 dB cm−1 at 1535 nm was achieved
