| Özet |
| The upconversion emission properties of Nb 2 O 5 modified tellurite-based glasses activated with Er 3+ , Tm 3+ , Ho 3+ , and Yb 3+ ions were studied. The glass samples wer obtained using melt-quenching method. The optical absorption spectra of the samples were collected in the 400-1100 nm wavelenth range at room temperature. The forbidden gap of the glasses were determined using the absorption spectra of the samples. The upconversion emission of samples were obtained under the 975 nm laser excitation and recorded in the 350-900 nm wavelength range. Three primary colors were simultaneously obtained from the samples under the 975 nm excitation. The CIE-1931 coordinates and the correlated color temperaatures of obtained upconversion emissions were also determined using the upconversion emission spectra. |
