Structural characteristics and dielectric response of some zinc tellurite glasses and glass ceramics

Structural, thermal and optical properties of TeO2–ZnO–CdO–BaO glasses doped with VO2+

“…2, it is clear that molar volume (V m ) of the present glasses increased from 25.067 to 28.932 cc/mol with the increase of BaO content. OPD of glass samples were calculated using the following expression and are tabulated in Table 2.…”

“…But few of TeO 3 units contain a NBO with a double bond to tellurium, two bridging oxygen ions. The bands observed around 700-800 cm -1 region are due to the formation of Zn 2 Te 3 O 8 units in the glass matrix [27,28]. It can be observed from Fig.…”

A review of the structures of oxide glasses by Raman spectroscopy

“…The increase of Na 2 O content in tellurite glasses results the 40 transformation of TeO 4 tbps to TeO 3 tps due to increased number of NBOs [233][234]. The formation of Zn 2 Te 3 O 8 units changes the bands positioned at 295, 343 and 700-800 cm -1 [239][240][241]. The study of xNa 2 O.…”

Synthesis and different optical properties of Gd 2 O 3 doped sodium zinc tellurite glasses

“…The dopant ions maintain majority of their individual properties in the glass matrix. Due to low melting point (T m ) and glass transition temperature (T g ) [6,7], preparation of tellurite glasses are comparatively easier than other glass families. Optical absorption in solids occurs due to the absorption of photon energy by either the lattice (or phonon) or by electrons.…”
