Special Issue Information

Dear Colleagues,

The field of theoretical chemistry has undergone remarkable advancements in recent years, revolutionizing our approach to materials science and engineering. Computational methods have become indispensable tools for understanding, predicting, and designing materials with tailored properties at the atomic and molecular levels, accelerating the discovery of novel materials and also providing deep insights into the fundamental principles governing the behavior of materials.

It allows us to explore complex systems and phenomena that may be challenging or impossible to study experimentally, offering a cost-effective and time-efficient complement to traditional experimental methods.

As we face global challenges in many different applications, the role of theoretical chemistry in materials science becomes increasingly crucial.

This Special Issue is intended to act as a contributor to this discussion and to future developments on this theme. We are pleased to invite you to present cutting-edge research at the intersection of theoretical chemistry and materials science in all classes of materials, highlighting how theoretical and computational approaches are revolutionizing our understanding of material properties, design, and applications. This Special Issue will cover a wide range of topics, including quantum chemical calculations (density functional theory and ab initio methods), molecular dynamics simulations, and machine learning techniques applied to materials research.

Full papers, communications, and reviews are all welcome. Research areas may include (but are not limited to) the following: novel theoretical methods, predictive modeling of material properties, and computational studies that guide experimental work in materials development. By bringing together diverse perspectives from theoretical chemists, materials scientists, and computational researchers, this Special Issue seeks to foster interdisciplinary collaborations and advance the field of materials science through theoretical insights.

The collection of papers will serve as a valuable resource for researchers, highlighting the latest advancements and future directions in theoretical chemistry as applied to materials research.

I look forward to receiving your contributions to this exciting Special Issue.

Upconversion (UC) luminescence in doped lanthanide nanocrystals is associated with the energy migration (EM) process within clusters of dopant ions. The process of the synthesis of core–shell nanocrystals occurs at elevated temperatures, promoting the diffusion of the dopants into the shell accompanied by the decay of dopant clusters. The details of this unwanted effect are poorly understood. In this paper, we theoretically study a model of the diffusion of dopant ions in a nanocrystal using Monte Carlo (MC) simulations. We characterize the diffusion, spatial neighboring relations and clustering of dopant ions regarding the function of reduced temperature and MC time of the heating process. The dopants undergo a weak subdiffusion caused by trapping effects. The main results of this study are as follows: (i) the phase diagram of the variables reduced the temperature and MC time, which separates the enhanced and limited cluster-driven EM regimes, and (ii) a dependence of the average nearest distance between Yb ions as a function of reduced temperature, the concentration of Yb ions and MC time was found. In both cases, the requirements for an effective EM are formulated. Full article
