Abstract

B2O3 - TeO2 - ZnO- Na2O glasses doped with 0% to 5% mol of Mn2+ were prepared using the melt quenching method. Measurements of X-ray diffraction confirmed the non-crystalline structure of samples. Optical properties were analyzed by excitation and emission spectra. The emission spectra showed an intense emission in the 610 nm (red region), a corresponding transition of 4T1(G)→6A1 (G). From the results of emission spectra, we determined the color coordinates of all samples excited by 410nm wavelength. The results indicated that B2O3- TeO2 - ZnO-Na2O glasses doped Mn2+ ions can provide a new platform to design and fabricate novel luminescent materials for color LED, photonic devices, and display applications.
