LaNaSyLum is a research team led by Prof. Tomasz Grzyb, operating within the Department of Rare Earths at Adam Mickiewicz University in Poznań, Poland.
We develop next-generation lanthanide-based luminescent nanomaterials designed to control light–matter interactions at the nanoscale.
Our research integrates materials chemistry, nanotechnology, and spectroscopy to create functional systems for energy conversion, sensing, and optoelectronic technologies.
Research Focus
We investigate luminescent nanomaterials whose properties are governed by lanthanide ions.
Our central research theme is up-conversion luminescence — the conversion of near-infrared radiation into higher-energy emission such as visible light.
Current research efforts focus on:
-
up-conversion to UV processes
-
up-conversion under excitation wavelengths above 1000 nm
-
persistent luminescent and up-conversion hybrid materials
-
up-converting nanoparticles as luminescent labels for targeting and tracking nano- and microplastics
These directions open new opportunities for solar energy harvesting and next-generation photonic technologies.
Alongside applied research, we explore fundamental questions concerning:
-
mechanisms of nanoparticle formation
-
energy transfer processes
-
spectroscopic behavior of lanthanide systems
Materials We Design
We engineer tailored nanostructures including:
-
core@shell nanoparticles
-
SiO₂-coated systems
-
surface-functionalized nanomaterials
-
stable luminescent colloids
Our goal is precise control over emission pathways, enabling tunable and dual-mode luminescence.

-
