Experimental observation of spatially resolved photo-luminescence intensity distribution in dual mode upconverting nanorod bundles.

ABSTRACT: A novel method for demonstration of photoluminescence intensity distribution in upconverting nanorod bundles using confocal microscopy is reported. Herein, a strategy for the synthesis of highly luminescent dual mode upconverting/downshift Y_1.94O₃:Ho³⁺_0.02/Yb³⁺_0.04 nanorod bundles by a facile hydrothermal route has been introduced. These luminescent nanorod bundles exhibit strong green emission at 549 nm upon excitations at 449 nm and 980 nm with quantum efficiencies of ~6.3% and ~1.1%, respectively. The TEM/HRTEM results confirm that these bundles are composed of several individual nanorods with diameter of ~100 nm and length in the range of 1-3 μm. Furthermore, two dimensional spatially resolved photoluminescence intensity
