Multiwavelength excitation confers synergistic upconversion effect from cooperative harvested energy transfer
Up to 3.5-fold enhancement in the upconversion (UC) luminescence of activators (Tm<sup>3+</sup> and Er<sup>3+</sup>) in an UC nanocrystal is observed when the sensitisers (Nd<sup>3+</sup> and Yb<sup>3+</sup>) are simultaneously excited. This is due to a coooperative harvested energy transfer to the activators from both direct and indirect-excited Yb<sup>3+</sup>.
