| 1 | Enhanced visible green and 1.5μm radiative emission of Er^(3+)ions in Li_(2)O-PbO-Al_(2)O_(3)-B_(2)O_(3) glasses for photonic applications显示文摘A series of Er^(3+)ions doped lithium lead alumino borate(LiPbAlB)glasses were synthesized via melt quench method and their structural,physical and optical properties were studied.Judd-Ofelt theory in correlation with the emission and absorption profiles was performed for the measurement of various radiative parameters for different transitions of Er^(3+)doped glasses.The as-prepared glasses show deep green(550 nm)as well as NIR(1532 nm)emission at 380 and 980 nm excitation wavelengths,respectively.The intensity of emission spectra increases with Er^(3+)ions concentration up to 1.5 mol%and beyond quenching is observed.The Dexter theory applied to the emission profiles reveals the interaction between Er^(3+)ions as dipole-dipole in nature.CIE color coordinates are found to fall in the green region of the visible spectrum.It is observed that 1.5 mol%of Er^(3+)ions concentration is optimum to exhibit the maximum quantum efficiency,branching ratios,gain bandwidth,emission cross-section,gain crosssection and aptly suitable for visible and NIR photonic applications. | Nisha Deopa Mukesh K.Sahu Sumandeep Kaur Aman Prasad K.Swapna Vinay Kumar R.Punia A.S.Rao | 2021 | Journal of Rare Earths2021，39，5： | 0 |
