1. A nanocomposite material, comprising:
a glass mixture comprising a first glass material and at least a second glass material, and
a plurality of optically active nanocrystals (NCs) comprising at least one of a rare earth and a transition metal doped material embedded within the glass mixture,
wherein the NCs comprise 0.01% to 20% by mass of the nanocomposite material, further wherein a refractive index (nf) of the glass mixture and a refractive index (nNC) of the NCs match within 0.002 at a selected wavelength.
