Abstract


Most of researcher interest to investigate tellurite glasses because of the capability as host laser. The tellurite glasses that develop
is Er:TZPBN [55TeO2 – 35ZnO – (5+x)PbO – 2Bi2O3 – (2-x)Na2O – Er2O3] with x = 0; 0,5; 1; 1,5; 2; 2,5 and 3% mol. This paper
describe the effect of PbO variation on optical absorption of Er:TZPBN. The Er:TZPBN glass had been fabricated by using melt
quenching technique. After annealing and polishing proccess, we characterized the optical absorption of glass. The result of the
characterization showed that the optical absorption increased with increasing PbO. Based on optical absorption data, the optical band
gap energy decreased with decreasing PbO concentration. The value of optical band gap energy for this composition showed that this
samples can use as the semiconductor material.
