主な論文
 Vacancy clusters in diamond studied by electron spin resonance (2004) Iakoubovskii, Konstantin; We report on the electron spin resonance characterization of dominant paramagnetic defects created in pure diamond by neutron irradiation followed by annealing at temperatures above 1150 degreesC....

 Diamond as a magnetic field calibration probe (2004) Maes, J, Iakoubovskii, Konstantin; Hayne, Manus; Moshchalkov, VV; An optical method is proposed for the calibration of pulsed magnetic fields using photoluminescence from synthetic diamond. Generally, the pulsed magnetic field profile is reconstructed by measuring...

 Annealing of vacancies and interstitials in diamond (2003) Iakoubovskii, Konstantin;  Kiflawi, I, Johnston, K, Collins, A, Davies, G; Optical absorption (OA) and electron spin resonance measurements have been performed on IIa, Ib, IaA and IaB type diamonds irradiated by 3 MeV electrons. OA reveals that the GR1 system in diamond is...

 Characterization of defects in monocrystalline CVD diamond films by electron spin resonance (2003) Iakoubovskii, Konstantin; Suzuki, K, Kuwabara, J, Sawabe, A; Electron spin resonance (ESR) measurements on free-standing monocrystalline CVD diamond samples allowed us to deduce the symmetry of the previously reported KUL1 and KUL3 centers as trigonal and...

 Electron spin resonance characterization of a multi-nitrogen complex in diamond (2002) Iakoubovskii, Konstantin; The W27 centre has been characterized by means of electron spin resonance in natural diamond. The centre exhibits spin S = 1, a large spin-spin coupling constant D = 99 mT, and a complex hyperfine...

 Characterization of hydrogen and silicon-related defects in CVD diamond by electron spin resonance (2002) Iakoubovskii, Konstantin; , Stesmans, Andre; Two hydrogen and two silicon-related defect centers were detected and characterized by electron-spin resonance (ESR) in diamond films grown by chemical vapor deposition. Observation of hyperfine...

 ESR and photo-ESR study of defects in CVD diamond (2002) Iakoubovskii, Konstantin; Stesmans, Andre; Nesladek, M, Knuyt, G; Two hydrogen and two Si-related defect centers were detected and characterized by electron spin resonance (ESR) in diamond films grown by chemical vapor deposition. Observation of hyperfine...

 Symmetry of the hydrogen-vacancy-like defect H1 in diamond (2002) Iakoubovskii, Konstantin; Stesmans, Andre; Suzuki, K, Sawabe, A, Yamada, T; The H1 center has been characterized by electron spin resonance in monocrystalline diamond grown by chemical vapor deposition. The results are consistent with the model of one hydrogen atom trapped...

 Dominant paramagnetic centers in O-17-implanted diamond (2002) Iakoubovskii, Konstantin; Stesmans, Andre; Electron spin resonance (ESR) measurements were performed on nitrogen-free diamond films grown by chemical vapor deposition and on diamond single crystals, irradiated by O-17 ions and annealed in the...

 Synthesis and characterization of sol-gel derived ZnS : Mn2+ nanocrystallites embedded in a silica matrix (2002) Bhattacharjee, B, Ganguli, D, Iakoubovskii, Konstantin; U0013498, Stesmans, Andre; Chaudhuri, S; Synthesis and characterization of undoped and Mn2+ doped ZnS nanocrystallites (radius 2-3 nm) embedded in a partially densified silica gel matrix are presented. Optical transmittance,...

 Chemical vapour deposition diamond studied by optical and electron spin resonance techniques (2002) Iakoubovskii, Konstantin; Stesmans, Andre; This work discusses the current situation in the study of bulk defects in diamond, grown by chemical vapour deposition (CVD), using optical absorption, luminescence, and electron spin resonance...

 Photoelectrical properties of the 1.682-eV and 3H centres in diamond (2001) Iakoubovskii, Konstantin; Stesmans, Andre; A narrow (few meV halfwidth) dip was observed at 1.682eV in the photocurrent (PC) spectra from diamond films grown by chemical vapour deposition (CVD). The shape of the dip matched that of the...

 Characterization of defects in as-grown CVD diamond films and HPHT diamond powders by electron paramagnetic resonance (2001) Iakoubovskii, Konstantin; Stesmans, Andre; Several defect centers, labeled as KUL1-7, have been detected by electron paramagnetic resonance in CVD diamond films and synthetic diamond powders. Their g values were determined relatively to the...

 ESR and optical evidence for a Ni vacancy center in CVD diamond (2000) Iakoubovskii, Konstantin; Stesmans, Andre; driaenssens, Guy; Characterization of a series of correlated electron-spin resonance (ESR) and photoluminescence (PL) lines in diamond grown by chemical vapor deposition is reported. The series consists of a Set of...

 Characteristic defects in CVD diamond: optical and electron paramagnetic resonance study (1999) Nesládek, M, Meykens, K, Haenen, K, Navratil, J, Quaeyhaegens, C, Stals, LM, ... Constant photocurrent method (CPM), electron paramagnetic resonance (EPR), and infra-red optical absorption (FTIR) techniques are used to study characteristic defects in the gap of free-standing...

 Effect of stress on optical and ESR lines in CVD diamond (1999) Iakoubovskii, Konstantin;  Stesmans, Andre;  Adriaenssens, Guy;  Provoost, R, Silverans, Roger;  Raiko, V; Correlation between the shape of Raman, photoluminescence (PL) and Electron Spin Resonance (ESR) signals in CVD diamond films was examined for both undoped and nitrogen-doped films. No correlation...
