applications that exploit near-IR spectroscopy, ranging from hand-held electronics to …

The production of white light based on a near-UV LED chip requires incorporating three
inorganic phosphors that emit in the blue, green, and red portions of the visible spectrum …

Short-wave infrared (SWIR) fluorescence could become the new gold standard in optical
imaging for biomedical applications due to important advantages such as lack of …

A variety of silicon-based nanostructures with dimensions in the 1–5 nm range now emit
tunable photoluminescence (PL) spanning the visible range. Achievement of high …

Many treatments of energy transfer (ET) phenomena in current literature employ incorrect
arguments and formulae and are not quantitative enough. This is unfortunate because we …

Solid-state lighting using laser diodes is an exciting new development that requires new
phosphor geometries to handle the greater light fluxes involved. The greater flux from the …

Quantum dots are ideally suited for color conversion in light emitting diodes owing to their
