[EN] Nd3+-doped RE3Ga5O12 (RE = Gd, Y, and Lu) nano-crystalline
garnets of 40-45 nm in size have been synthesized by a sol-gel method.
With the decrease of the RE atom size, the chemical pressure related to the
decreasing ...
[EN] The spatial distribution of Sr0.5Ba0.5Nb2O6 nanocrystals is analyzed in a borate-based glass-ceramic by a synchrotron hard X-ray nanoimaging tool. Based on X-ray excited optical luminescence, we examined 2D projections ...
