“…Furthermore, beside the size and shape of the NPs, the crystallographic phase appears to be a tuning parameter of particular importance for the antimicrobial effects of some oxides, especially for TiO 2 with the distinction between the anatase, rutile, and brookite structures [172][173][174][175]. Although reported to a lesser extent, the list of alternate oxides exhibiting potential in aPDT applications comprises CuO/Cu 2 O, MnO 2 , and rare earth oxides to mention just a few [141,[176][177][178][179][180].…”

Antimicrobial photodynamic therapy (aPDT) has become a fundamental tool in modern therapeutics, notably due to the expanding versatility of photosensitizers (PSs) and the numerous possibilities to combine aPDT with other antimicrobial treatments to combat localized infections. After revisiting the basic principles of aPDT, this review first highlights the current state of the art of curative or preventive aPDT applications with relevant clinical trials. In addition, the most recent developments in photochemistry and photophysics as well as advanced carrier systems in the context of aPDT are provided, with a focus on the latest generations of efficient and versatile PSs and the progress towards hybrid-multicomponent systems. In particular, deeper insight into combinatory aPDT approaches is afforded, involving non-radiative or other light-based modalities. Selected aPDT perspectives are outlined, pointing out new strategies to target and treat microorganisms. Finally, the review works out the evolution of the conceptually simple PDT methodology towards a much more sophisticated, integrated, and innovative technology as an important element of potent antimicrobial strategies.

“…Significant research has been conducted by exploring the REO element, its composition, host matrices, growth processes, and other experimental parameters (i.e., growth temperature, pressure, etc.) in a lab scale, whereas industrial applications require a more confirmed synthesis with some other concerns such as production cost and the efficient splitting of REOs. − Therefore, a piece of combined knowledge and understanding is required for a commercial viability. At present, there is a lack of accumulated studies concentrating on the applications, prospects, and challenges of REOs in optical applications.…”

In small- and large-scale industries, manipulable optical characteristics are desired. In this regard, rare-earth oxides (REOs) have been providing pragmatic attributes in terms of successful implementations and promising prospects throughout the last few decades. Currently, there is no comprehensive literature review on REOs that can aid researchers in focusing on industry-relevant emerging materials. Therefore, this review reports studies that have been able to experimentally utilize the physical, chemical, thermal, electronic, spectroscopic, and photocatalytic properties of REOs in the optical field. The brief and focused review finds that the most pronounced applications of REOs in the optical field are in white light and laser, while the prospective ground likely lies in optoelectronics, fiber optic applications, and miscellaneous repertoires that incorporate an innovative utilization of an electronic configuration of REOs. From the perspective of this review, the versatility of an REO in the optical field has become prominent and quantified by the successful implementations of REOs in white light and nonwhite light applications. Furthermore, the innovative applications of REOs include but are not limited to the development of solid-state optical devices, optoelectronic systems, and photocatalytic agents. Specifically, their futuristic applications are likely to be led by the development of stronger emission devices and the obtaining of flexible doping characteristics by several ions such as Li+, Eu3+, Dy3+, Nd3+, La3+, Yb3+, etc. at different levels, which will render the pathway for further exploration in this regard. However, the improvement in terms of methodological attributes requires a serious consideration of overcoming the limitation of thermal stability, lack of exploration of several types of lights, photodarkening in critical applications, lack of applicability at a wide range of temperatures, and so on. From an industrial perspective, it can be conjectured from the reported literature that the challenges will be overcome at a large scale within a few years due to the expedited technological advancements of the experimental repertoires, rendering the REO applications in the optical field reasonably economic and commercially viable. In short, this is the first review that objectively considers the applications and prospects of REOs, which will essentially invoke several studies to investigate the specific properties and viability of REOs in the optical field.
