Effect of Erbium Nanoparticles on Optical Properties of Zinc Borotellurite Glass System

Abstract

Erbium nanoparticles (NPs) doped zinc borotellurite glasses have been prepared by conventional melt-quenching technique with the chemical composition{[(TeO2)0.70(B2O3)0.30]1-x(ZnO)x}1-y(Er3O2)y(wherey=0.005,0.01,0.02,0.03,0.04,0.05). The structural properties of the prepared glasses were determined via X-ray diffraction (XRD) analysis and FTIR analysis. It was confirmed that the prepared glasses are amorphous. The bonding parameters of the glasses were analyzed by using FTIR analysis and were confirmed to be ionic in nature. The refractive index increases as the content of erbium NPs increases. The optical absorption spectra revealed that fundamental absorption edge shifts to longer wavelength as the content of erbium NPs increases. The value of band gap had been calculated and shown to be decreased with an increase content of erbium NPs. The Urbach energy was shown to be linearly increased with an increase content of erbium NPs oxides.

Comparison Study of Elastic, Physical and Structural Properties for Strontium Oxide and Manganese Oxide in Borotellurite Glasses for High Strength Glass Application

“…Tellurite oxide consists of two types of structural con guration units which are trigonal bipyramid indicating characteristics of boroxyl ring [9]. As the absorption spectra indicated the absence of boroxyl ring, BO 3 and BO 4 appeared as the substitution to the boroxyl ring [10]. In this work, the absorption band positioned at 1215 -1218 cm -1 was assigned to the trigonal B-O bond stretching vibration of BO 3 units from boroxyl groups.…”

“…The absorption band of pure borate glass, B 2 O 3 was centered at 806 cm -1 , indicating characteristics of boroxyl ring [9]. As the absorption spectra indicated the absence of boroxyl ring, BO 3 and BO 4 appeared as the substitution to the boroxyl ring [10]. In this work, the absorption band positioned at 1215 -1218 cm -1 was assigned to the trigonal B-O bond stretching vibration of BO 3 units from boroxyl groups.…”

Target dependent femtosecond laser plasma implantation dynamics in enabling silica for high density erbium doping

“…The linear variation of the EDTS layer thickness and refractive index, with respect to Er 3+ -ion content, is representative of the density of the target material used. The replacement of tellurium with heavier Er 3+ -ions in the target glass gives rise to the denser packing of the material 24 . This was confirmed by measuring the density of the target glasses using Accupyc 1330 Pycnometer that showed an increase in density from 5.2078 to 5.2507 g/cm 3 with the increased content of Er 3+ -ions from 0.125 to 1.25 mol%.…”
