Dilute magnetism in Zn1−xMnxTe nanocrystals grown in a glass template

Cd1−xMnxTe ultrasmall quantum dots growth in a silicate glass matrix by the fusion method

“…[8][9][10][11] Several types of semiconductor QDs have been doped with semimagnetic ions to form nanostructures, such as Cd 1Àx Mn x S, 12 Cd 1Àx Co x S, 13 Cd 1Àx Mn x Se, 14 Pb 1Àx Mn x Se, 15 Pb 1Àx Mn x S, 16,17 Zn 1Àx Mn x O, [18][19][20] and Zn 1Àx Mn x Te. 21 The exchange properties of Mn 2þ incorporated in II-VI, III-V, and IV-VI semiconductors QDs enhance as the quantum confinement effect increases. 3,11,22,23 Thus, the exchange interactions are more intensified in ultrasmall quantum dots (USQDs) than in traditional QDs.…”

Annealing time on carrier dynamics of ZnTe nanoparticles embedded in a near ultraviolet-transparent glass

“…In the panel (d) is shown the OA spectrum of the PZABP glass matrix (without doping), which is transparent in the near ultraviolet. It has been reported that the PZABP glass matrix is an adequate environment to induce a controllable growth of the ZnTe NCs [13][14][15]. Open circles represent the GAUSSIAN fit of the OA and PL spectra.…”

Solubility limit of Mn2+ ions in Zn1−x Mn x Te nanocrystals grown within an ultraviolet-transparent glass template

“…xMn (wt% of Zn)] was synthesized by the fusion method. This method consists of two sequential melting-nucleation processes which produce ensembles of nearly spherical nanoparticles embedded in a glass matrix, as described elsewhere (Dantas et al 2010(Dantas et al , 2012aSilva et al 2015Silva et al , 2016. The first step of sample preparation involved melting of powder mixtures of the precursor materials at 1300°C for 30 min in an alumina crucible and in an appropriate reducing atmosphere.…”
