Photoinduced piezooptics effect in TeO2–Ga2O3 glasses

Preparation and characterizations of glasses in the TeO2–Ga2O3–M2O (M═Li, Na, K) systems

“…The identified glass forming areas for binary systems (Ga 2 O 3 -TeO 2 and M 2 O-TeO 2 ) are in good accordance with the data in the literature mentioned in the introduction. 3,9,12 The glass forming domains of the ternaries are larger than predicted. 14 The exact boundaries of the glass forming areas depend on the technological conditions of sample preparation, among others on the purity of starting compounds and the changes of the melt composition during the melting process (due to evaporation of the constituents of the melt or contamination by the material of the crucible, e.g.).…”

“…In the binary system of (100−x)TeO 2 -xGa 2 O 3 , the glasses are formed for compositions with x between 5 and 25. [9][10][11] However, for x above 20 only small pieces of glassy material can be obtained by an ultra-fast quenching method using a twin-roller. 9 Alkaline oxides, acting as pure glass network modifiers that usually lower the glass melting temperature, can also be added to TeO 2 to promote tellurite glass formation.…”

In (100−x)TeO 2 -xM 2 O binary systems, where M is Li or Na, glasses can be formed with x between 5 and 30 in the case of Li 3 , and between 7.5 and 25 in the case of Na.…”

“…One of the promising stabilizers is gallium oxide, whose role in glass is usually intermediate, that is, it acts as a modifier that is also able to participate in the formation of the glass network. In the binary system of (100− x )TeO 2 – x Ga 2 O 3 , the glasses are formed for compositions with x between 5 and 25 9–11 . However, for x above 20 only small pieces of glassy material can be obtained by an ultra‐fast quenching method using a twin‐roller 9 …”
