We studied the influence of doping with 4d and 5d elements on the optical and photo‐
induced properties of Bi12SiO20 (BSO) crystals. Doping with Ru, Rh and Re does not …

We report on optical and electrical measurements contributing for a better characterization of
the relevant properties of undoped Bi 2 TeO 5. Optical absorption, dark conductivity …

We report the recording of optical gratings on photorefractive \rmBi_2\rmTeO_5 Bi_2TeO_5
crystals using λ=532\,\rmnm λ= 532nm wavelength light. We studied the behavior of this …

The work in thesis is a step towards a better understanding of the photorefractive effect in Bi
$\sb {12} $ SiO $\sb {20} $ crystals. It primarily deals with a discrepancy which was found …

We present the results of a comparative experimental study of optical and photorefractive
properties at room temperature of four nominally undoped, single‐crystal, commercially …

The influence of low (∼ 10− 4 wt.%) chromium concentrations on the photorefractive
properties of sillenite crystals have been studied by holographic techniques. The presence …

Bi 12 SiO 20 are widely used in optical devices, spatial-time light modulators and as
holographic media depending on their properties in a wide spectral range. This work deals …

We present experimental characterization of the dependence of the photorefractive
response on alternating field frequency in BSO. We report a frequency dependence which …

Bi 12 TiO 20 single crystals doped with Cd, Cu, P, Cr, Ag, Al were grown by the top-seeded
solution growth method (TSSG). The electrical measurements were carried out on different …

Stationary and photoinduced spectra of optical absorption and photoconductivity of undoped
and doped (by Cu-, Ag-and Mo-ions) Bi12SiO20 crystals have been investigated in a …
