Erbium‐doped fiber amplifiers ; are important optical components for telecommunications. That films of nanoparticulate ZnO colloids are a potential route for the preparation of planar micropatterned Er 3+ amplifier components is demonstrated by the synthesis of micropatterned films of Er@ZnO, i.e., Er ;3+ entrapped in ZnO nanoparticles, with variable refractive index and high optical gain (see Figure).
