Optical transitions of different Mn-ion pairs in ZnS

Optical properties of sol–gel fabricated Mn/SiO2 nanocomposites: Observation of surface plasmon resonance in Mn nanoparticles

“…According to Refs. [13][14][15][16][17] Mn 2+ ions cause the characteristic absorption and photoluminescence bands in the visible spectral range, and J 2 -J 4 bands correspond to the light absorption by Mn 2+ ions in silica matrix in tetrahedral coordination and J 5 band corresponds to light absorption in Mn 2+ ions in silica matrix in octahedral coordination. According to Ref.…”

“…[7][8][9][10]. There exist many works reporting the optical properties of Mn containing nanocomposites [11][12][13][14][15][16][17]. The optical properties of such Mn containing nanocomposites are determined by optical transitions in manganese ions and oxides.…”

Mn2+‐Doped CdSe Quantum Dots: New Inorganic Materials for Spin‐Electronics and Spin‐Photonics

“…[60] At elevated Mn 2þ concentrations, Mn 2þ -Mn 2þ exchange interactions also provide a mechanism for circumventing the spin forbiddeness because the transition only needs to conserve the total spin of the cluster. [61,62] These mechanisms are not usually very efficient, and transitions between the 6 A 1 ground state and all ligand field excited states remain largely forbidden. 6 A 1 !…”

Synthesis and optical properties of monodispersed Ni2+-doped ZnS nanoparticles

“…The doped luminescent nanoparticles are of strong interest for possible use in optoelectronics such as LEDs and lasers or as novel phosphors because of their interesting magnetic (Kennedy et al 1995;Counio et al 1996;Igarashi et al 1997;Feltin et al 1999) and electro-optical properties Pohl and Gumlich 1989;Devisschere et al 1995;Yu et al 1998). Recently, the doped nanomaterials have been largely studied due to their widespread applications in various devices such as sensors, solar cells, lasers, photocatalysts, photodetectors, IR detectors, optical communication, color television, flat panel display, phosphors, light emitting diodes, etc.…”
