Laser-induced crystallization in glass is

Crystallization of Stoichiometric SbSI Glass

“…In order to form specific single crystal patterns in glass, the first important consideration is the choice of a composition which both forms glass easily and crystallizes only into the desired phase. If the chemical composition of the desired crystal is located in the glass‐forming region, then the basic conditions of laser crystallization are satisfied a priori, and patterned crystals may be formed without significant difficulty . However, in general, this condition may not be satisfied.…”

“…C RYSTALLIZATION by laser irradiation is a novel method to produce 3-D crystal architectures within preselected regions of a glass [1][2][3][4][5][6][7][8][9][10] and to construct active optical elements. Thus far, this technique has been applied primarily to oxide glasses with compositions typically used for glassceramics applications.…”

“…If the chemical composition of the desired crystal is located in the glass-forming region, then the basic conditions of laser crystallization are satisfied a priori, and patterned crystals may be formed without significant difficulty. [1][2][3][4][5][6][7][8][9][10] However, in general, this condition may not be satisfied. For example, antimony sulphoiodide (SbSI) is a chalcogenide compound which exhibits high values of the dielectric constant, spontaneous polarization, and pyroelectric and pyro-optic coefficients.…”

Effect of Al2O3 addition on the formation of perovskite-type NaNbO3 nanocrystals in silicate-based glasses

“…The laser-induced crystallization technique used in this study has previously been applied to various glass systems and compositions [e.g., [23][24][25][54][55][56][57][58]. For example, lines consisting of highly oriented LiNbO 3 crystals have been successfully patterned on the surface of Li 2 O-Nb 2 O 5 -SiO 2 glasses by laser irradiations [56].…”

The influence of heat treatment conditions on the structure and properties of (As₂Se₃)_100-x(SbSI)_x glasses and composites on their basis

“…Інтерес до вивчення халькогенідних некристалічних матеріалів на основі сегне-тоелектрика SbSI [1] викликаний широки-ми можливостями їх практичного застосу-вання в системах запису інформації, опто-електроніці, інфрачервоній та нелінійній оптиці, сенсориці [2][3][4][5][6][7][8]. У цьому плані ці-кавими є стекла і композити в системі As 2 Se 3 -SbSI.…”
