3.5-fold enhancement in luminescence was achieved through synergistic upconversion when both sensitizers were stimulated, maximizing energy transfer.
This study showcases the significant role of cooperative energy transfer mechanisms involving Nd3+ and Yb3+ as sensitizers to activate Tm3+ and Er3+.
Analysis employs a detailed observation of the upconversion behavior within the nanocrystals, underscoring the complexity of luminescent interactions.
Findings suggest prospects for enhanced applications in photonics and optoelectronics through improved light energy harvesting.

Implication

Observational analysis shows 3.5-fold enhancement in luminescence with coordinated activation of sensitizers, indicating improved energy transfer.

Abstract

Up to 3.5-fold enhancement in the upconversion (UC) luminescence of activators (Tm3+ and Er3+) in an UC nanocrystal is observed when the sensitisers (Nd3+ and Yb3+) are simultaneously excited. This...
