ZnSe nanocrystals embedded in KDP crystals

ZnSe nanocrystals were elaborated in KDP dielectric crystalline matrix by addition of ZnSe powder to the mother solution during crystal growth. Optical absorption spectra show a band situated at 270 nm indicating impurity of KDP. X-ray diffraction confirm ZnSe inclusions incorporation, the average s...

Description
Summary:ZnSe nanocrystals were elaborated in KDP dielectric crystalline matrix by addition of ZnSe powder to the mother solution during crystal growth. Optical absorption spectra show a band situated at 270 nm indicating impurity of KDP. X-ray diffraction confirm ZnSe inclusions incorporation, the average size was estimated to 13 nm. Micro-Raman measurement showing widening and blue-shifting of LO and TO ZnSe phonon due to size effect.
