Thermodynamic stability evaluation via cohesive energy and defect formation energy confirmed that the TbV₂ color center possesses the most favorable atomic configuration. Electronic structure calculations were further carried out on this optimized geometry to characterize charge transfer and interatomic bonding between Tb and carbon atoms. By systematically analyzing the band structure, density of states, and spin–orbit coupling effects, the energy-level scheme of the diamond TbV₂ color center was established. The ⁷F_J manifold acts as the ground state, while the ⁵D₄ manifold corresponds to the excited state. The zero-phonon line (ZPL) energy for the radiative transition from the ⁵D₄ excited state to the ⁷F_J ground state was calculated as 2.28 eV, corresponding to green fluorescence at a wavelength of 544 nm. To systematically explore how nitrogen (N) and boron (B) dopants modulate the luminescence performance of TbV₂ color centers, all thermodynamically stable N-doped, B-doped, and N/B co-doped configurations were screened via cohesive and formation energy calculations. Subsequent electronic structure simulations were implemented to clarify the dependence of optical transition energy levels on dopant species and doping concentration on the basis of these stable defect geometries. Moreover, the ZPL positions and corresponding fluorescence wavelengths of various doped TbV₂ color centers were theoretically predicted. Our theoretical investigations verify that the diamond TbV₂ color center can serve as a high-performance single-photon source.</p></div>","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"55 11","pages":"9938 - 9947"},"PeriodicalIF":2.8,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the structural analysis, the synthesized samples were analysed using x-ray diffraction (XRD). From the analysis, it was found that the sample has a perovskite-like structure. To study the morphology of the synthesized samples and for elemental mapping, scanning electron microscopy (SEM) coupled with energy-dispersive x-ray spectroscopy (EDS) was used. SEM confirmed that the particles differed in size and shape. Using EDS, it was confirmed that Gd, Nb, V, and O were present in the desired ratio in the sample. The photoluminescence properties and decay kinetics were investigated to evaluate its potential for solid-state lighting applications. The excitation spectrum was monitored at 605 nm and is dominated by a broad and intense host charge transfer band (CTB) centred at 312 nm. This originates from the vanadate (VO₄)³⁻ and niobate (NbO₄)³⁻ groups. Upon excitation at 312 nm, the phosphor exhibits 4<i>f</i> → 4<i>f</i> transitions which are characteristic transitions of Sm³⁺, with the most prominent emission peak located at 605 nm (⁴G_5/2 → ⁶H_7/2). The dominance of the host-related band over the direct Sm³⁺ transitions indicates an efficient energy transfer process from the GdNb₂VO₉ host lattice of the activator ions. The luminescence decay curve of the ⁴G_5/2 level follows mono-exponential behaviour with a calculated lifetime of 0.664 ms, suggesting a uniform distribution of Sm³⁺ in the host matrix. Also, the calculated CIE 1931 chromaticity coordinates confirm high colour purity in the orange-red region. Concentration quenching was observed for the 7 mol.% Sm³⁺-doped sample, which is because of non-radiative energy migration between Sm³⁺ ions, cross relaxation processes, and multipolar interaction, likely dipole–dipole type. Furthermore, the high colour purity under 407 nm excitation indicates that the emission is strongly dominated by the characteristic orange-red transitions of Sm³⁺ ions, demonstrating the effectiveness of Sm³⁺ incorporation in tuning the emission colour of the host lattice. In this study, time decay characteristics were studied in detail. The estimated value of quantum efficiency was found to be of the order of 74.8% to 78.8%. These results demonstrate that GdNb₂VO₉:Sm³⁺ is a suitable candidate as a red-emitting component for near-UV-excited white light-emitting diodes (w-LEDs).</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"55 10","pages":"8994 - 9007"},"PeriodicalIF":2.8,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
