LOMS.cz computational platform for high-throughput classical and combinatorial Judd-Ofelt analysis and rare-earth...

Area of Science:

• Spectroscopy
• Materials Science
• Computational Physics

Background:

• Judd-Ofelt (JO) theory is fundamental for rare-earth [Formula: see text] transitions but lacks standardized computational methods.
• Precise and reproducible determination of JO parameters remains a significant challenge in the field.

Purpose of the Study:

• To introduce LOMS.cz, an open-source computational platform designed to standardize Judd-Ofelt calculations.
• To address the need for reliable parameter extraction and prediction of optical properties in rare-earth spectroscopy.

Main Methods:

• Automated computation of JO parameters, transition probabilities, branching ratios, and radiative lifetimes.
• Development of a dynamically expanding database of experimentally validated JO parameters.
• Implementation of a novel Combinatorial JO (C-JO) analysis algorithm for optimal band combination identification.

Main Results:

• Demonstrated rapid screening of spectroscopic parameters using the LOMS.cz framework.
• Enabled enhanced reliability in predicting optical properties of rare-earth materials.
• Established a standardized platform combining automated analysis with experimental validation.

Conclusions:

• LOMS.cz provides a standardized computational framework for Judd-Ofelt calculations.
• The platform accelerates the discovery and optimization of rare-earth-based photonic and optoelectronic materials.
• Integration of automated analysis and experimental validation enhances research reproducibility and efficiency.
