6. Optical properties; MDO 183 fluctuations in source intensity and atmospheric absorption, but of course would be affected by imperfections in the glass. 6.2. Results This section presents the infrared absorption spectra of oxide tellurite and fluorotellurite glasses studied. These are followed by emission spectra of previously heat treated Er +3 - doped fluorotellurite glasses. Refractive indicies of oxide tellurite and fluorotellurite glasses are then presented. 6.2.1. Infrared spectroscopy 6.2.1.1. Infrared spectroscopy of oxide tellurite glasses Infrared spectroscopy of glasses of the series (80-x)TeO2-10Na2O-10ZnO-xMO mol. %, where MO is PbO or GeO2 Fig. (6.6) shows infrared spectra of glasses in the series (80-x)TeO2-10Na2O-10ZnO- xMO mol. %, where MO was PbO or GeO2, for MOD006 (x = 3 mol. % PbO), MOD010 (x = 5 mol. % PbO) and MOD012 (x = 5 mol. % GeO2).

Strongly hydrogen bonded OH = strong OH and weakly hydrogen bonded OH = weak OH. It can be seen the multiphonon edge (taken from the x-axis where the absorption coefficient reaches 2 cm -1 ) for these glasses occurred at around 1667 cm -1 (6 µm). All three glasses exhibited absorption bands in the infrared region due to hydroxide (OH) groups in the glass. Three OH bands were seen, the positions depending on the degree of hydrogen bonding of the OH in the glass: strongly hydrogen bonded OH (strong OH), weakly hydrogen bonded OH (weak OH), and free OH. A higher intensity asymmetric band was seen at around 3000 cm -1 (3.33 µm). This band was identified as a combination band of weakly H-bonded OH and free OH. The lower intensity band at around 2270 cm -1 (4.41 µm) was due to strongly H-bonded OH in the glass. The doublet which appeared at around 2800 cm -1 (3.57 µm) for glass MOD010 was identified as CH / CH2 / 2000 1750 1500 1250 1000 750 500 250 0 Loss / dB.m -1
