title: [Study on the spectral properties of nanocrystals Dy0.5Sr0.5CoO3-Y].
abstract: The spectral properties of nanocrystallines Dy0.5Sr0.5CoO3-Y were studied. The results show that the band edge of emission spectra is blue shift when the size of particles decrease to nanometer. The infrared absorption peak fission of nanocrystallines and the XRD diffraction peak of nanocrystallines were widen than microcrystallines. It was appeared as quantum size effect.
