Orientation of nanoscale objects can be measured by examining the polarized emission of
optical probes. To retrieve a three-dimensional (3D) orientation, it has been essential to …

We design planar silicon antennas for controlling the emission rate of magnetic or electric
dipolar emitters. Evolutionary algorithms coupled to the Green Dyadic Method lead to …

Rare-earth ion doped crystals are of great significance for microsensing and quantum
information, while the ions in the crystals emit light with spontaneous partial polarization …

Narrow‐band Purcell enhancement for electric and magnetic dipole emitters by high‐order
Mie resonances up to the magnetic and electric octupole modes of a silicon nanosphere …

We present a modified version of the Judd-Ofelt theory, which describes the intensities of ff
transitions for trivalent lanthanide ions (Ln 3+) in solids. In our model, the properties of the …

NaYF_4: Eu nanorods with high aspect ratios are elaborated and optically trapped using
dual fiber optical tweezers in a counterpropagating geometry. High trapping efficiency is …

Polarized luminescence has many applications in energy saving, displays, communication
and other fields. Here, electrically tunable polarized luminescence of aligned Eu (tta) …

Excitation polarized upconversion luminescence (EPUL) from lanthanide ions has attracted
considerable attention due to its wide applications in microfluidics, single particle tracking …

Achieving reversible large‐span photoluminescence regulation still faces difficulties due to
limitations in the design or preparation conditions of related materials. Herein, a universal …

Near-and far-field optical properties of silicon nanostructures under linear polarization
