Concentration dependent fluorescence quantum efficiency of neodymium doped phosphate glass matrix

Thermo-optical properties of Nd3+ doped phosphate glass determined by thermal lens and lifetime measurements

“…Compared to other glass matrices |C| ¼ 3.94 W À 1 is a better result than that found for ZBLAN (12.5 W À 1 ) and Q-98 (4.1 W À 1 ) glasses [10]. After determining C, K¼ 5.9 Â 10 À 3 W/cm K [29] could be used to calculate ds/dT¼(1.5 70.1) Â 10 À 6 K À 1 , which agrees with the previously found value of ds/dT¼1.6 Â 10 À 6 K À 1 [29]. η R and Eq.…”

“…C¼ 3.94 W À 1 and η R ¼0.92 were obtained from the linear fit, using Eq. (5) and 〈λ em 〉¼1065 nm [29]. Since C is proportional to ds/dT, it can be used as an indicator of the system's capacity to handle thermal distortions in the pump beam wavefront.…”

Thermally enhanced photoluminescence for heat harvesting in photovoltaics

“…1). In addition, we have measured the sample's EQE to be ∼30%, whereas Nd 3+ doped glasses are reported to achieve PL EQE's of almost 100% (refs 20, 21, 22) at relatively low Nd 3+ concentration levels of 1 wt % .…”

Using a fuzzy system in the study of the luminescence and potency of neodymium ions

“…The study of the luminescence of neodymium ions embedded in an in vitro hostess presents an interesting case due to its physical and optical properties, allowing applications such as optical fibers, optical filters, and active medium lasers [1][2][3][4][5][6][7]. Several studies on rare-earth ions are found in the literature, particularly the neodymium ion (Nd 3 ), which is frequently utilized in optical devices in the fields of scientific research, industry, and medicine.…”
