The influence of synthesis methods and conditions on the phase composition, structure, morphology and dispersion of phosphor powders based of different crystal matrices, as well as on the luminescent properties of crystal phosphors has been established. It is shown that the optimal method for the synthesis of crystalline phosphors with high quantum radiation efficiency is solid-phase synthesis, while for biomedical applications wet synthesis methods should be used.   Product Description popup.authors Hreb Vasyl M Zahrai Andrii I Luchechko Andriy P Stadnik Vitalii Ye Turchak Svitlana L Ubizskii Sergii B popup.nrat_date 2021-09-02 Close
