Item Role of Defects in Formation of the Luminescence Properties of Zinc Molybdate Crystals(2017-05-29) Hizhnyi, Y.; Nedilko, S.; Nikolaenko, T.; Nagornyi, P.; Boyko, R.; Boyko, V.; Taras Shevchenko National University of Kyiv, 64/13 Volodymyrska Str., 01601 Kyiv, Ukraine; National University of Life and Environmental Sciences of Ukraine; Geroiv Oborony Str., 03041 Kyiv, UkraineItem Electronic structure and luminescence mechanisms in MIMIII(MoO4)2 molybdates(Видавництво Львівської політехніки, 2012) Hizhnyi, Yu.; Nedilko, S.; Chornii, V.; Nikolaenko, T.; Zatovsky, I.; Terebilenko, K.; Boiko, R.The mechanisms of intrinsic luminescence in several molybdate crystals of MIMIII(MoO4)2 (MI = Li, Na, K; MIII =Bi, Y, Fe) type are revealed in complex experimental and theoretical studies. The luminescence spectroscopy studies under VUV synchrotron excitations are applied together with the electronic structure calculations carried out by the FLAPW method. Simultaneous analysis of diffuse reflectance and luminescence excitation spectra is used for determination of the energy gap (Eg) values of the crystals. It is found that the molybdate groups MoO4 2- play dominant role in the processes of intrinsic luminescence in studied molybdate compounds.Item Theoretical modelling of the luminescence spectra of oxide crystals AWO4 (A=Zn, Pb) with defects(Видавництво національного університету „Львівська політехніка”, 2009) Nikolaenko, T.; Hizhnyi, Yu.; Nedilko, S.
