“…Thus, the PL spectral distribution is a function of a multilevel and multiphonic process. 40 The photoluminescence of tungstates is substantially related to configurations presented by the [WO 4 ] 2− clusters in terms of structural distortions that promote changes in the structure of energy bands by the insertion of intermediate levels in the band gap. According to Marques et al , 41 the excitation process occurs by energy absorption in a low energy state [O(2p)] and excitation to higher energy states [W(5d)].…”

“…The optical band gap energy is assumed by αhv ∝ ( hv – E gap ) 1/ k , where α is the absorbance, h is the Planck constant, v is the frequency, and k is indicated for the different kind of transitions. Molybdates are normally reported with a permitted direct electronic transition, , thus the band gap energy from the MgMoO 4 samples was analyzed assuming k = 1/2. The band gap values estimated in our samples are under what can be found in the literature.…”

Intrinsic white-light photoluminescent rare-earth free materials are promising candidates in the field of environment-friendly optical devices. They are important because whitelight materials such as LED devices contribute to safe-energy from photoluminescent emission, which simulates daylight in brightness and comfort at home and/or within industrial environments. Thus, it is a natural path that experimental and theoretical efforts can be combined to understand the best way to reach superior photoluminescent properties in materials. The ultrasonic spray pyrolysis method was employed in this study to synthesize shapeoriented MgMoO 4 nanoparticles with different morphologies after heat treament, which exhibits singular photoluminescence emission spectra with intrinsic white-light emission. For a deep discussion on the electronic structure, quantum mechanical calculations at the DFT/B3LYP level were performed such as in monoclinic β-MgMoO 4 bulk in its surfaces combined with the Wulff construction. The wideband approach was considered for investigating fundamental and excited electronic states (singlet and triplet). The morphological analysis indicates a thermal-active morphological modulation that induces the stabilization of hexagonal planes such as (100) and (010). The DFT calculations enabled us to understand the charge-transfer process along [MgO 6 ] and [MoO 4 ] clusters from characterizing fundamental singlet (s) and the excited singlet (s*) and triplet (t*) electronic states.
