Growth of SrS thin films by pulsed-laser deposition

Blue shift in band gap and photoluminescence of pulsed laser deposited SrS:Ce/quartz thin film nanophosphors

“…Generally, thin film phosphors offer several advantages over the conventional powder phosphor screens, including high resolution, thermal stability, uniformity, density, and possibly a much lower susceptibility to charging [8]. There are several reports available on the synthesis of SrS based thin films on different substrates using pulsed laser deposition (PLD) [8,9], e-beam evaporation [10], RF sputtering [11], atomic layer epitaxy [12], etc.…”

“…There are several reports available on the synthesis of SrS based thin films on different substrates using pulsed laser deposition (PLD) [8,9], e-beam evaporation [10], RF sputtering [11], atomic layer epitaxy [12], etc. Since in low dimensional systems, electrons and holes are spatially confined causing quantum confinement effects, energy levels and hence optical properties become considerably different from their bulk counterparts [13][14][15].…”
