Two types of lead-fluoride nano-glassceramics doped with rare-earth ions (Tm, Ho, Pr, Er, Yb) have been developed and
synthesized. The size of crystalline phase achieved up to 40 nm. Spectral and luminescence properties of nanoglassceramics
have been investigated. It was shown, that emitting probabilities of different transitions changed during
thermal treatment. The entry of rare-earth ions in crystalline phase resulted in a broadening of emission spectra. For
example, the bandwidth of emission spectrum at 1.55 mkm achieves 70 nm for Er-doped nano-glassceramics. RE-doped
nano-glassceramics are promising candidates for different photonics applications, sensors, fiber and waveguide lasers.
