“…Single crystals of YAG doped with rare-earth (RE) ions, usually Nd 3+ , Yb 3+ , Er 3+ , Ho 3+ or Pr 3+ ions emit efficiently in the NIR region and are still among the most important solid state laser materials presently used. 2 Moreover, YAG doped with other RE ions (Tb 3+ , Ce 3+ ) is widely used as phosphor and scintillating material. 3 4 Finally, in the last decade polycrystalline YAG ceramics with properties comparable to single crystals have been very actively developed.…”

Transparent Pr-doped YAG nanoceramics composed of grains with an average size of about 42 nm, were fabricated with the Low Temperature High Pressure (LTHP) sintering technique using the corresponding nanopowders as the starting materials. The structure of the nanoceramics was analyzed by X-ray diffraction (XRD). The effect of the sintering conditions on the structural properties is discussed on the basis of the changes of the spectroscopic properties of Pr3+ ions. In particular, the intensities and decays of the emission transitions originating from the (3)P0 and (1)D2 levels are investigated and correlated with structural properties of the material, such as microstrains produced by the high-pressure process.
