Structural and time resolved emission spectra of Er3+: Silver lead borate glass

Structural and luminescence behaviour of Er3+ doped telluro-fluoroborate glasses

“…Recently glasses doped with trivalent rare earth (RE) ions have been widely investigated by many researchers due to their potential applications in solid state lasers, optical amplifiers, color display devices and fibre optical communication systems etc., [1][2][3]. The complete knowledge on spectroscopic properties of optical materials such as transition probabilities stimulated emission cross-section, branching ratios are essential to find new optical devices or to enhance the performance of the existing devices [4,5].…”

Structural and spectroscopic behavior of Er3+/Yb3+ co-doped boro-tellurite glasses

“…The band at 1205 cm − 1 is assigned to the symmetric stretching vibrations due to BO 2 O − triangles linked with BO − 4 tetrahedral units [30]. The Raman band at around 1123 cm − 1 is mainly due to the presence of diborate groups in the borate network [31]. The band observed at 1026 cm −1 is due to the stretching modes of some of the terminal oxygen (B-O − ) belonging to the BO 2 O − metaborate triangles [32].…”

Structural, UV-VIS-NIR Luminescence And Decay Associated Spectral Profiles Of Sm3+ Doped Calcium Phosphate Glass

“…its local site and distribution within the host material. [20]. Therefore, the present paper reports on the structural, UV-VIS-NIR emission and time-resolved emission spectral profiles of Sm 3+ doped calcium phosphate glass.…”

“…Addition of Sm 3+ ions increases the density of glasses due to creation of BO − 4 units [16]. Previous work by the authors has addressed the structural and photoluminescence studies of different host glasses [17][18][19][20][21]. Time-resolved emission spectrospy (TRES) enables the emission spectra to be determined at specified times during the decay [20].…”

“…Previous work by the authors has addressed the structural and photoluminescence studies of different host glasses [17][18][19][20][21]. Time-resolved emission spectrospy (TRES) enables the emission spectra to be determined at specified times during the decay [20]. This provides a technique, which is suitable to study the structure via the kind of active ion present and its local environment, ie.…”
