Abstract

The influence of compression on the edge of self absorption of AgBr single crystals was studied. The measurements were performed at a temperature of −180°C. The shift of the edge of self absorption was studied both in the field of elastic and plastic deformations. The shift of the absorption edge towards the UV end of the spectrum was determined in the field of elastic deformations and towards the i.r. end in the field of plastic deformations. After the ending of the deformation and after unloading the crystal the return of the absorption edge towards the original position was observed.

Abstract

Изучалось влияние давления на длинноволновой край границы собственного поглощения монокристаллов AgBr. Измерения производились при температуре −180°C. Смещение длинноволнового края границы собственного поглощения изучалось как в области упругих, так и в области пластических деформаций. В области пластических деформаций было обнаружено смещение длинноволновой границы собственного поглощения в направлении к ультрафиолетовой части спектра, в области упругих деформаций — в направлении к инфракрасной части спектра. После окончания деформации и отдыха кристалла в обеих областях деформации наблюдалось возвращение длинноволнового края границы собственного поглощения в направлении первоначального положения.
