A systematic investigation of deep levels in undoped and doped (Fe, Fe/V, excess of Bi)
single crystals of Bi12 GeO20 (BGO) has been performed by photoinduced current transient …

The analysis of thermally stimulated conductivity (TSC) measurements performed on
''pure''Bi12GeO20 (BGO) and BGO doped with gallium is presented. The TSC data show …

Charge transfers between traps in undoped Bi12GeO20 (BGO) crystals have been
investigated so as to complete our previous studies concerning the mechanism of the …

D&a from measurements of optical absorption, photoconductivity, dark conductivity,
thermally stimulated conductivity (TSC), and thermoluminescence JTL) on samples of …

When subjected to measurements of temperature‐dependent dark conductivity and
thermally stimulated currents, undoped and lightly doped Bi12GeO20 (BGO) and Bi12SiO20 …

Thermally stimulated current (TSC) from nominally undoped Bi12GeO20 (BGO) crystals was
measured as a function of the uv excitation temperature and time. The results were …

Localized levels play a major role in the electro‐optic properties of Bi12SiO20 (BSO)
crystals. The activation energy of trapping levels was studied by different laboratories using …

We have measured the temperature dependence of the electron mobility between∼ 200
and 300 K in undoped and 0.3% Fe-doped Bi 12 GeO 20 (BGO) and undoped Bi 12 SiO 20 …

The spectroscopic properties of Eu3+ doped Bi12GeO20 (BGO) sillenite bulk crystals that
were grown by the low-thermal-gradient Czochralski technique (LTG Cz) were investigated …

Cathodoluminescence and photoluminescence of Bi12SiO20 and Bi12GeO20 samples are
studied. Both kinds of samples show a dark orange central part or core. Emissions in the …
