“…It can be seen from Table 1 that the value of Ω 2 decreases gradually with the increase of heat-treated temperature indicating Er 3+ ions are successfully incorporated into LaOF nanocrystals. On the other hand, the value of Ω 6 , which is proportional to the rigidity of the host, increases in the transition from glass to GCs indicating the physical properties of samples are improved gradually [21].…”

Transparent oxyfluoride glass ceramics (GCs) containing LaOF:Er 3+ nanocrystals were synthesized. X-ray diffraction (XRD), Raman spectra and transmission electron microscope (TEM) confirmed the formation of LaOF nanocrystals in glass matrix. Energy dispersive spectrometer (EDS) results and Judd-Ofelt (J-O) intensity parameters demonstrated the incorporation of Er 3+ into LaOF nanocrystals. Enhanced 2.7 μm emission was achieved upon excitation with a 980 nm laser diode (LD). Upconversion, near-infrared emissions, and energy transfer mechanisms were studied to elucidate 2.7 μm emission behaviors. The enhanced 2.7 μm emission is most likely ascribed to the incorporation of Er 3+ ions into the low phonon energy LaOF nanocrystals. The excellent optical properties of this GC material indicate that it is a promising candidate for mid-infrared fiber lasers. , "Origin of near to middle infrared luminescence and energy transfer process of Er 3+ /Yb 3+ co-doped fluorotellurite glasses under different excitations," Sci.
