Near UV-light excitable inorganic phosphors are widely recommended for white-light emitting diode (wLED) applications. Here in this paper we prepared Eu3+ doped SrAl2O4 phosphors with various concentrations of Eu3+ (1–5 mol%) by a green combustion technique. The phase structure and purity of...

Lithium niobite (LiNbO3) nanostructure were successfully synthesized by chemical bath deposition method (CBD) and then decorated with silver nitrate (AgNO3) through UV activation method at different immersion durations (5, 15, 25, 35, and 45 s). The silver nanoparticles (AgNPs) effects on the ...
Of the 17 sites, only three (Lauder, Palmer, and Thessaloniki) have near-complete data coverage for the full period from 1996 to 2018. However, six others (Barrow, Hoher Sonnblick, Boulder, Mauna Loa, Arrival Heights and South Pole) have only a few years of missing data over that ...
Similar to embossing, point UV printing works equally well when picking an image or logo because it is a random “blind” pattern that does not follow the lines of the print area below. You can make your creative juice flow, in fact, we really recommend it; take a look at this example...
White LED prototypes with tunable correlated color temperature and color-rendering index values were realized by controlling the amount of phosphors. The presented results indicated the potential application of Ca_2SiO_4:Ln (Ln = Ce~(3+), Eu~(2+), Sm~(3+)) phosphors in near-UV white LED...
There has been a near log rise in microneedle patents over the last few years. This has resulted in a crowded intellectual property space with many patents and applications overlapping. The recent microneedle patent space can be roughly divided into microneedles that take a sample and those that ...
Thermally Stable Transparent Sol−Gel Based Siloxane Hybrid Material with High Refractive Index for Light Emitting Diode (LED) Encapsulation. Chem. Mater. 2010, 22, 3549–3555. [Google Scholar] [CrossRef] Raman, R.K.; Gurusamy Thangavelu, S.A.; Venkataraj, S.; Krishnamoorthy, A. Materials...
, a flow meter, a balance connected with a data acquisition system to interpret the filtrate flow rate, a pressure gauge measuring the equilibrium pressure exerted on the filtration cell, a Philips UV-A light (Actinic BL TL-K 40 W/10-R) emitting near-UV radiation at long wave UV-A (...
