Photoetchable glass is a very promising material for the production of components for a wide variety of microsystems. High aspect ratio microstructures can be realized by using slightly modified semiconductor equipment and relatively low fabrication

The shift of the lowest quantized state ▿ E 1 in quantum dots (QDS) is connected with the crystallite radius R , determined, e.g. by X-ray techniques. Theory gives ▿ E 1 = CE B ex ( a B π / R ) 2 with C = 0.67. C varies from 0.3 to 10 when using

Within the last few years there has been an increasing interest in materials exhibiting non-linear optical effects. Various semiconductors and crystals are known for large non-linear coefficients but the intense search for even more efficient and cos

X-ray absorption fine structure (XAFS) spectroscopy of a zinc potassium silicate glass containing small quantities of cadmium (0.5%), selenium (0.4%) and sulphur (0.1%) and heat treated in various ways has enabled the atomic environments of these ele

We present results concerning optical properties of II–VI semiconductor quantum dots. In pump and probe beam experiments at room and helium temperature we found no holeburning but a strong bleaching of both maxima in the absorption spectrum up to 7

Optical, infrared, EPR, and thermoluminescence emission spectra are measured for color centers in natural and X-ray irradiated sanidine. These and the kinetics of color center formation and destruction indicate the presence of several kinds of closel

Various radiation defects were characterized and analyzed by electron paramagnetic resonance (EPR) in 15 feldspars of different compositions after X-ray irradiation. A hole center on oxygen adjacent to two aluminum ions is formed in most feldspars, e

Up to four broad thermoluminescence emission bands were observed in X-ray irradiated feldspars of different composition. Slow decrease of emission after X-ray irradiation indicates the presence of shallow traps in most feldspars. The glow curves were
