“…The positions of the emission and excitation bands are in excellent agreement with the results of Ref. [3]. Manavbasi and LaCombe [3] attributed 283 and 315 nm excitation bands to the Pb 2 + ion trapped exciton and A band ( 1 S 0 -3 P 1 ), respectively.…”

“…Since this band is observed for most of the activators, it cannot be attributed to the intra-configurational transition 4f 8 ( 7 F 6 )-4f 7 5d 1 . This excitation band is related to the host and previously attributed to the exciton absorption near the activator [3].…”

“…Except for Bi, all the activators studied in this work show strong 283 nm excitation band. Manavbasi and LaCombe [3] found that the 283 nm absorption band is related to the host absorption. There is compelling evidence to suggest that the 283 nm excitation band is related to this absorption.…”

Thermoluminescence (TL) analysis of gamma‐irradiated SrZnO2:Dy nanophosphors elucidates the presence of various trapping centers in forbidden band. Raman and Fourier‐transformed infrared spectra indicate effect on vibrational structure upon doping. Complex glow curves are obtained at varying gamma radiation doses, exhibiting glow features in low (50–180 °C) and high (220–400 °C) temperature regions. The deconvolution of glow curves indicates the presence of TL peaks at ≈100, 143, 202, 269, and 337 °C. The effect of Dy doping is observed as emergence of new glow feature at ≈143 °C. The substitution of trivalent Dy into SrZnO2 host having divalent cations is proposed to be creating DynormalX1+ (X = Sr, Zn) electron traps and normalVnormalX2− hole traps, along with hitherto existing intrinsic defects. The concentration quenching of TL signal is perceived at 3 mol% Dy doping, whereas comparing glow curves for all samples at saturation dose indicate quenching of low‐ and high‐temperature glow features at different doping concentrations. The theoretical track interaction model and empirical three trap one recombination center (3T1R) model is used to explain former and latter effects, respectively. A schematic band model is proposed to predict the trap distribution upon Dy inclusion, responsible for observed TL in SrZnO2:Dy nanophosphors.

SrZn(NCN)2, the first example of a ternary post‐transition metal carbodiimide, was prepared by a solid‐state metathesis reaction. The crystal structure was solved from PXRD data and found to adopt the orthorhombic (Cmcm) BaZnSO structure, a high symmetry modification of that expressed by the oxide analogue SrZnO2. Locally, SrZn(NCN)2 features ZnN4 tetrahedra and SrN6 trigonal prisms similar to those in quarternary LiSr2M(NCN)4 (M = Al3+ and Ga3+) phases, however, the overall topologies are distinct with single chains in the former and double chains in the latter. Electronic structure calculations indicate an indirect bandgap of about 2.95 eV in SrZn(NCN)2, slightly lower than the experimentally observed bandgap of 3.4 eV in SrZnO2 and consistent with a greater degree of covalency. The structural similarities between SrZn(NCN)2 and oxychalcogenide analogues highlight the pseudochalcogenide character of NCN2– and suggest that the title compound may serve as a template for accessing novel ternary carbodiimides featuring tetrahedrally coordinated transition metals.
