“…2 shows the excitation spectra for S2, S4 and singly doped ZnS samples recorded in the range of 300-550 nm for emission wavelength fixed at 596 nm. For the Sm 3+ doped samples, the spectra show maximum intensity for the excitation peak at 403 nm corresponding to 6 H5/2→ 6 P3/2 transition of Sm 3+ , because of the highest oscillator strength of the transition [2,14,15]. This fact is also revealed by the absorption spectra in Fig.1.…”

“…Based on absorption and emission bands of intra-configurational f-f transitions, the energy level intensities of rare earth ions in several host media have been described and estimated quantitatively by using the Judd-Ofelt (J-O) theory [4]. Study of the optical properties of the rare earth ions in different host materials provides fundamental data that include transition positions, transition probabilities, branching ratios, etc.…”

“…The intensity of these emission bands increases with concentration up to 2.0 mol% of Nd 3+ ions. Further increase of Nd 3+ concentration has lead to the decrease of emission intensity due to concentration quenching at higher dopant levels which is normally observed in RE 3+ doped glasses/crystals [36,37].…”
