“…In conclusion crystals quality demonstrated high efficiency in transmission spectra and are suitable for application on silicon based solar cell devices [2,5]. Rare earth lanthanides Nd³⁺-Eu³⁺ ions materials have great optical quality and exhibit less transmission of light through the Nd-Eu nanoparticles in comparison to single Eu³⁺ and Nd³⁺ nanoparticles due to upconversion processed as reported in previous research [2].…”

“…In our research, our goal is to develop crystal nanoparticles from rare earth materials that have the capabilities to transmit less light and absorb more light that is normally lost due reflection, thermalization, and transmission losses. Silicon based solar cells use electromagnetic radiation and devices mainly absorb visible light to covert that energy to power solar cells devices [2]. Super crystals nanoparticles can absorb more light waves due to specific frequencies within the electrons due to visible and infra-red emission that tend to vibrate when incident light excites meta-materials [3].…”

Developing new technologies is essential for advancement in solar cell technologies due to their ability to only absorb light mainly in the visible light spectrum. Super crystals Nd³⁺- Eu³⁺ optical characteristics display higher absorption of light waves than single crystals of Eu³⁺ and Nd³⁺ due to a two-photon absorption energy transfer mechanism known as upconversion. Super crystals Nd³⁺- Eu³⁺ display higher absorption due to fewer light waves being transmitted through materials as reported in spectra data. Transmission spectra data reflects that Nd³⁺- Eu³⁺ nanoparticles are great candidates to enhance light absorption in solar cell devices.

“…Indeed, the detailed research on the photon upconversion process of lanthanide ion‐doped UCNPs in phototheranostics, their synthetic strategies, and their photophysical and photochemical features are already reviewed comprehensively elsewhere. [ 37,46–48 ] Also expert readers in the field outside aPDT are directed to read excellent reviews to get the detailed knowledge on the fundamental principles of UCNPs applied for antibacterial phototherapy. [ 28,49–52 ] This review presents rather unique antimicrobial theranostics using UCNPs and its multifunctional hybrid systems.…”

“…Trivalent lanthanide (Ln 3+ ) ion possesses upconversion luminescence (UCL) features due to the presence of partially occupied 4f‐orbitals and filled 5s and 5p orbitals, [ 46 ] where multiband electronic transitions can easily occur through them (Figure 2B). [ 53 ] The electronic transitions between these closely spaced orbitals can result in spin‐forbidden sharp luminescence bands and long‐lasting excited states (≈µs–ms order).…”

Developing photoactive nanosystems against microbial infection and its therapeutic application is compromised by the lack of suitable materials or molecular dyes activatable at biofriendly NIR light. In this direction, the upconverting nanoparticles based on core–shell lanthanide‐doped nanoclusters are developed synthetically to achieve a broad range of NIR‐active phototherapeutic antimicrobial agents. This review illustrates antimicrobial photodynamic therapy (aPDT) and multimodal therapy by NIR photoirradiation, generated by lanthanum doped upconverting nanoparticles (UCNPs). The objective herein is to discuss the insights in developing the UCNPs for designing efficient aPDTs and their efficacies against emerging antibiotic‐resistant bacterial colonies and their biofilms, drug‐resistant fungi, and viruses. The biosafety and biocompatibility of UCNPs at both in vitro and in vivo level are also presented in detail. Finally, our perspectives on the ways of future material engineering needed for the effective translation into their real‐world applications are also commented.

“…hoton upconversion (UC), the conversion of low-energy into higher-energy photons by use of lanthanide-doped materials, has been of rapidly growing interest in the fields of materials chemistry and physics within the past 50 years 1 . Extensive research has been done on understanding the theory of the UC process [1][2][3][4] and on material development, predominantly nanocrystals [5][6][7][8][9][10][11][12][13][14][15] . By now, UC is exploited in a broad range of applications ranging from bioimaging 13,[16][17][18][19][20] , theranostics [21][22][23][24] , security 20,25,26 , data storage 27 , and data analysis 28 to photovoltaics 13,15,19,20,[29][30][31] .…”

Experimental validation of a modeling framework for upconversion enhancement in 1D-photonic crystals

et al. 2021

Photonic structures can be designed to tailor luminescence properties of materials, which becomes particularly interesting for non-linear phenomena, such as photon upconversion. However, there is no adequate theoretical framework to optimize photonic structure designs for upconversion enhancement. Here, we present a comprehensive theoretical model describing photonic effects on upconversion and confirm the model’s predictions by experimental realization of 1D-photonic upconverter devices with large statistics and parameter scans. The measured upconversion photoluminescence enhancement reaches 82 ± 24% of the simulated enhancement, in the mean of 2480 separate measurements, scanning the irradiance and the excitation wavelength on 40 different sample designs. Additionally, the trends expected from the modeled interaction of photonic energy density enhancement, local density of optical states and internal upconversion dynamics, are clearly validated in all experimentally performed parameter scans. Our simulation tool now opens the possibility of precisely designing photonic structure designs for various upconverting materials and applications.
