Luminescence Spectra of Mn 2 + Doped in
Luminescence data for 6 manganese doped langbeinites, Aj B2 + (S04)3 , are reported. They are consistent with octahedral symmetry of the impurity center (substitutional in B site), although for the host lattice the B site is known to show three-fold axial (distorted octahedral) symmetry only. In accordance with previous conclusions from EPR data the luminescence parameters indicate structural r...
متن کاملTransient Characteristics of Luminescence from CdS-Doped Glass
Japanese Journal of Applied Physics, 31 (2A) (1992) 375-376 Transient Characteristics of Luminescence from CdS-Doped Glass Tadaki Miyoshi Department of Electrical and Electronic Engineering, Yamaguchi University, Tokiwadai, Ube 755 (Received August 16, 1991; accepted November 16, 1991) Time-resolved luminescence spectra were measured at 300 K and 77 K in CdS-doped glass under N2 laser excitatio...
متن کاملLuminescence Properties of Eu and Mn Doped Sr2MgSiO5 Phosphors
Eu ions doped Sr2MgSiO5 phosphors, and EuMn ions-doped Sr2MgSiO5 phosphors were prepared via high-temperature solid state reaction method and sol-gel process, respectively. Luminescent mechanism and characteristics of all samples were studied. The results showed that lattice structure of Eu ion-doped Sr2MgSiO5 samples was pyramidal system. The influence of flux on luminescence properties of Eu ...
متن کاملEnhancing luminescence in lanthanide-doped upconversion nanoparticles.
The enthusiasm for research on lanthanide-doped upconversion nanoparticles is driven by both a fundamental interest in the optical properties of lanthanides embedded in different host lattices and their promise for broad applications ranging from biological imaging to photodynamic therapy. Despite the considerable progress made in the past decade, the field of upconversion nanoparticles has bee...
متن کاملTuning luminescence of 3d transition-metal doped quantum particles: Ni+2: CdS and Fe+3: CdS
The room-temperature photoluminescence of Cd1−xMxS (M=Ni, Fe) nanoparticles were investigated. Compared with the photoluminescence of CdS which peaks at 475 nm, the photoemission of CdS:Fe nanoparticles was peaking at 537 nm because of Fe acting as luminescent centers. On the other hand, the green emission (503 nm) of CdS:Ni attributed to the T2g(D)→ A2g(F) raditive transition. With the increas...
