Growth of CsI(Tl) crystals doped with Ca and Tm and investigation of its scintillation characteristics
In this work, the growth of CsI(Tl) crystals as gamma detector was performed using vertical Bridgman method with Ca and Tm co-dopants. For evaluation of the growth crystals, X-Ray Diffraction (XRD), photoluminescence and thermoluminescence spectra as well as recorded gamma spectra were employed. In addition, the scintillation properties including energy resolution, scintillation decay time, abs...
متن کاملOptical Reorientation in Dye-doped Liquid Crystals
The nonlinear optical properties of liquid crystals received considerable attention in the past decades and were reviewed by various authors. Harmonic generation in liquid crystalline phases and optical reorientation of nematics are examples of nonlinearities studied in detail. The present paper deals with the latter effect, paying special attention to the influence of absorption on the process...
متن کاملSite-selective upconversion in Ho3+ doped fluorite crystals MF2 (M=Ca,Sr,Cd)
With tunable dye laser (620-660 nm) excitation, the site-selective upconversion properties of 0.1 mole% Ho3+ doped CaF2, SrF2 and CdF2 monocrystals were studied at 77K. Three distinct luminescence centres (C4,,, C3v and cluster) were identified for both CaF2 and SrF2 crystals, whereas only one cluster centre was detected for CdF2. The upconversion mechanism for the isolated H O ~ + single site ...
