Changes in color appearance caused by chromatic adaptation were measured with a wide range of adapting fields. Observers viewed a 39'-55' annular test field composed of an admixture of lights from the red phosphor and the green phosphor of a CRT. The annular mixture field was centered and superimposed upon a 4.7 degrees steady, circular background field. After the observer was completely adapte...

The phosphor dip-transfer coating method is simple and flexible for transferring a preanalyzed volume of phosphor gel, which can be beneficial to the high angular color uniformity (ACU) of white light-emitting diodes (LEDs). The crux of this method is the volume control of the phosphor gel; however, the critical factors which influence the volume control remain unrevealed. In this paper, we con...

Single-phase cool white-light emitting BaNb2O6:Dy(3+) phosphors have been synthesized via a conventional solid-state reaction method and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) observations and spectrofluorophotometric measurements. XRD and Rietveld structural refinement studies confirm that all the samples exhibit pure orthorhombic structure [space group...

This paper describes essential results for thermographic phosphorescence applications in laser diagnostics at extremely high temperatures for reacting and non-reacting flows. Promising results have been attained although these applications perform poorly in hostile environments. An experiment was conducted to investigate the viability of non-contact temperature measurements based on thermograph...

Figure 1: Sketches of the molecules of the individual species comprising the investigated LiPF6 in EC:DMC electrolyte solution. Hydrogen atoms are white, carbon atoms grey, oxygen atoms red, phosphor atoms orange, and fluoride atoms blue. The arrows indicate the molecular size, and include the molecules’ van der Waals radii. Insights into the Molecular Scale Structure of Electrolyte-Metal Oxide...

Up-Conversion Luminescence Feng Liu, Jiahua Zhang and co-workers explore an innovative way of using visible light for disinfection application by introducing a transmissive remote phosphor-converted source phosphor composite film, which gives ultraviolet-C emission upon excitation with blue lasers. More information can be found in article number 2200106.

Electroless composite coatings used for achieving of high hardness, lubrication properties, non-stick surface, abrasive coating applications that by impregnation of soft and hard particles into Ni matrix. Electroless Nickel-phosphorous coatings properties and performance is greatly affected by the amount of phosphorus in them. The phosphor in this coating usually varies from 1 to 13 percent. In...
