Optical spectroscopy of thulium-doped oxyfluoroborate glass

Optical absorption and fluorescence properties of Tm3+-doped K–Mg–Al phosphate glasses for laser applications

“…As can be seen from Table 2, it is observed that the trend of JO parameters (˝2 >˝4 >˝6) is found to be same for phosphate [1], germanate [2], PKBAT [16], fluorophosphate [27], borate [28], tellurite [29], ZBLAN [30], ZBLALi [31], indium-fluoride [31], CaBaMg aluminate [32] and fluoro-indate [33] glasses. The trend of˝2 >˝6 >˝4 is noted for PKMAT similar that of oxyfluoroborate [11] glasses and the trend of˝6 >˝2 >˝4 was observed for tellurite [12] glass. It is well known that '˝2' is the most sensitive to local structure and glass composition and its value is indicative of the amount of covalent bonding between Ln 3+ ions and ligand anions [36].…”

“…[5][6][7][8][9][10]. The important 1 D 2 → 3 F 4 transition of Tm 3+ ion gives blue emission at ∼450 nm in both down-and upconversions [11,12] which is useful for high capacity data storage optical devices.…”

Spectroscopic properties of Er3+ in a oxyfluoride glass and upconversion and temperature sensor behaviour of Er3+/Yb3+-codoped oxyfluoride glass

“…Upconversion of infrared-to-visible in rare-earth doped oxyfluoride glasses has been extensively investigated [1][2][3][4][5][6], due to the potential applications of these materials in areas like visible lasers, optical data storage, color display, under-sea optical communications and sensors [7][8][9][10][11][12][13][14]. Among the rare-earth ions, Er 3 + ion is one of the important active ions due to its convenient energy level structure exploitable in upconversion processes.…”

Optical transitions of Ho3+ in oxyfluoride glasses and upconversion luminescence of Ho3+/Yb3+-codoped oxyfluoride glasses

“…Upconversion luminescence of rare-earth doped various glasses has been extensively investigated [1][2][3][4][5][6][7][8][9][10], due to the potential applications of these materials in areas like visible lasers, optical amplifiers, optical data storage, color display, biomedical diagnostics and sensors, etc. [11][12][13][14][15][16].…”
