In 2006, Ramanathan et al . demonstrated 1 electric-field mediated tunable photoluminescence from ZnO nanorods, with potential for application as novel sources of near-ultraviolet radiation.

Certain ?-conjugated macrocycles, reported by Swager and co-workers at MIT, were also found to form J-aggregates and exhibited exceptionally high photoluminescence quantum yields.
43.
"' Mechanochromic luminescence ( ML ) "'references to intensity and / or color changes of ( solid-state ) stimuli while its photoluminescence can be quite different.
44.
This technique allows the characterization of different aspects of photovoltaic cells : external quantum efficiency with the help of photoluminescence and electroluminescence hyperspectral measurements combined with a spectral and photometric absolute calibration method.
45.
One idea that Knight is toying with is to build a simple oscillator _ a circuit that repeatedly turns on and off _ and to combine it with the genes that create photoluminescence proteins.
46.
When it meets other interstitials it aggregates into larger complexes of two and three split-interstitials, identified by electron paramagnetic resonance ( R1 and O3 centers ), optical absorption and photoluminescence.
47.
Most common " white " LEDs convert blue light from a solid-state device to an ( approximate ) white light spectrum using photoluminescence, the same principle used in conventional fluorescent tubes.
48.
Interest in polyfluorene derivatives has increased because of their high photoluminescence quantum efficiency, high thermal stability, and their facile color tunability, obtained by introducing low-band-gap co-monomers.
49.
One of the advantages of excitation with an electron beam is that the band gap energy of materials that are investigated is not limited by the energy of the incident light as in the case of photoluminescence.
50.
In 2016 using the coherent diffraction imaging ( CXDI ) beamline at ESRF ( Grenoble, France ), the researchers quantified the porosity of large faceted nanocrystalline layers at the origin of photoluminescence emission band in the infrared.
