Lanthanide Complex Film Luminescence Data for Temperature Sensing

A PDF document details experimental data on visible-light-excited thermosensitive luminescent films containing a europium complex. The work evaluates temperature sensitivity, reporting a measured sensitivity of 18.97 μs/K and a reversible operating temperature range of 298–353 K. The dataset was authored by Aleksandr S. Krupin and shared on figshare in March 2026.

Use Cases

• Analyze the relationship between temperature and luminescence intensity for the Eu(III) complex films to calibrate a sensor model.
• Evaluate the excitation band at ∼400 nm to assess compatibility with inexpensive visible light sources in the 390–425 nm range.
• Model the impact of J-aggregate formation on the luminescence lifetime parameter for material optimization.
• Benchmark the reported temperature sensitivity of 18.97 μs/K against other luminescent thermometry materials.

Strengths

• Reports a specific, high temperature sensitivity measurement of 18.97 μs/K for the luminescent films.
• Defines a clear, reversible operational temperature range of 298–353 K (25–80 °C).
• Documentation includes detailed methodology for film vitrification and excitation by visible light at ∼400 nm.

Limitations

• The dataset is a 364.8 KB PDF document, not a structured, machine-readable table, limiting direct computational analysis.
• Sample size and specific numerical data points (e.g., individual intensity readings per temperature) are not explicitly quantified in the provided description.
• The material's performance is described for a specific Eu(III) complex film, limiting generalizability to other compounds.
