Showing upon excitation with light of 370 nm at a wavelength of lambda max a maximum emission intensity i0 and at lambda max+30 nm an emission intensity i, such that i is less than or equal to 0.20 i0doi:US6730243 B2A CsBr:Eu phosphor showing a narrow emission spectrum upon UV-...
Reference light with a known wavelength lambdatau emitted from a semiconductor laser light source 7 is branched in two with a halfmirror 4 and after impinged into the interferometers 8 and 5 respectively, the respective parts of the light are detected with a photodetecting section 9 and a ...
PROBLEM TO BE SOLVED: To provide a light wavelength multiplexer/demultiplexer capable of correcting a central wavelength deviation arising during production. ;SOLUTION: In a light wavelength multiplexer/demultiplexer provided with a substrate 101, at least one input waveguide 102 formed on the substrate...
The emitted light is a result of the recombination of excitons within the intrinsic heterojunction of ZnS phosphor powders in an alternating current electric field, whereas the light wavelength is tuned by dopants in the ZnS lattice and the voltage-induced luminance by the ionic conductor does not...
the wavelength (\(100\lambda\)), so the propagation factor\({{{\mbox{e}}}^{{{\mbox{i}}}{kz}}\)is negligible. Next, we choose a transverse reference point (\({{{\bf{r}}}_{\perp {{\mbox{ref}}},{z}\)) close to the optical axis (\(R\approx 0\)), so that the phase...
The same operational voltage Uf is applied to a number of the LEDs. The brightness (lv) of each and the dominant wavelength (lambdadom) are measured. The LEDs are then grouped in accordance with these measurements. The measured values (lv, lambdadom) in each group has a defined and limite...
In this study, sea surface skylight spectral reflectance rho(lambda) was retrieved by means of the non-linear spectral optimization method and a bio-optical model. The spectral variability of rho(lambda) was found to be mainly influenced by the uniformity of the incident skylight, and a model...
Two InGaAs quantum wells are included in a (lambda) -AlGaAs cavity between two AlGaAs/AlGaAs Bragg mirrors. The top n-doped Bragg mirror has 4 pairs, the bottom one is p-doped like the substrate and has 20 pairs. The detuning between the source emission wavelength and the Fabry Perot ...
The wavelength peak appears at 558 nm, and the full width at half maximum (FWHM) is measured as 61 nm, spreading from 532.5 to 593.5 nm, at the laboratory temperature of 28 ºC (Supplementary Table 1). It has been hypothesized that different species of fireflies emit light at slightly ...
transmission plane forming a speckle pattern generated by multiple scattering. The measured diffuse reflectance is ≈0.3, which suggests that low-power light propagation is governed by diffusive transport34. At the operating wavelength, the measured absorption coefficient of the bioprinted spheroids without...
