The novel heterometallic aggregates [Ag(8)Cu(2)(C(2)C(6)H(4)X)(6)(PPh(2)C(6)H(4)PPh(2))(6)][PF(6)](4) (X = H, 1; OMe, 2; NMe(2), 3) were prepared by the self-assembly reactions starting from simple precursors. These compounds consist of the central [Ag(6)Cu(2)(C(2)C(6)H(4)X)(6)](2+) clusters capped by two tripodal fragments [Ag(diphosphine)(3)](+). The solid state structures of complexes 1 and ...
با پیشرفت و همگانی شدن کامپیوترها، نیاز برای انتقال داده به کامپیوترها افزایش پیدا کرد. پورت ها وسیله ای برای ارتباط با device های جانبی متنوع از جمله کیبورد، میکروفون و ... هستند. با گذشت زمان پورتها به منظور پشتیبانی از گستره وسیعی از device ها، پیشرفته تر و کابردی تر شدند. با روی کار آمدن پورت usb دراواسط دهه 1990، این پورت توانست جایگزین سایر پورت های موجود شود چراکه این پورت ها به تنوع نا...
Front Cover: In article number 2200392, Andrea Pucci and co-workers effectively utilize red emissive commercially available Eu3+ chelate (Lumilux SDP Red, Lu Red) as fluorescent pigments to produce thin film luminescent solar concentrators based on waterborne polymer matrices. Maximum external quantum device efficiencies of 4–4.5% 0.70% are respectively gathered with Red contents less than 15 w...
wileyonlinelibrary.com to authenticate are therefore important for the protection of brands and valuable documents such as bank notes, diplomas and certifi cates. Luminescent tags or labels are appreciated security elements for protecting authenticatable articles. One way to incorporate luminescent materials as luminescent security elements is to print them with luminescent inks. [ 2 ] Nowadays...
A novel class of luminescent cyclometalated gold(III) alkynyl complexes has been demonstrated to possess EL properties and has been employed in the roles of electrophosphorescent emitters or dopants of organic light-emitting diodes (OLEDs) with high brightness and efficiency.
As proposed in the LUCIFER project, ZnSe crystals are attractive materials to realize scintillating bolometers aiming at the search for neutrinoless double beta decay of the promising isotope 82Se. However, the optimization of the ZnSe-based detectors is rather complex and requires a wide-range investigation of the crystal features: optical properties, crystalline quality, scintillation yields ...
In this paper we develop a model to describe the emission profile from randomly oriented dichroic dye molecules in a luminescent solar concentrator (LSC) waveguide as a function of incoming light direction. The resulting emission is non-isotropic, in contradiction to what is used in almost all previous simulations on the performance of LSCs, and helps explain the large surface losses measured i...
The development and application of optical luminescent methods devices will help obtain information quickly objectively about the level Fusarium infection agricultural plants. For previously obtained ranges, spectral characteristics excitation luminescence wheat, barley, oats various degrees were measured. dependences flows on approximated by linear regression models relative sensitivities dete...
Luminescent solar concentrators (LSCs) generally consist of transparent polymer sheets doped with luminescent species. Incident sunlight is absorbed by the luminescent species and emitted with high quantum efficiency, such that emitted light is trapped in the sheet and travels to the edges where it can be collected by solar cells. LSCs offer potentially lower cost per Wp. This paper reviews res...
Luminescent security labels are effective platforms for protection of consumer goods from counterfeiting. However, the lifetimes such approaches limited due to narrow-band photoluminescent features label elements, which can be used technology disclosure. In this paper, a novel concept application non-linear white-light luminescence hybrid metal–semiconductor structures fabricated by direct femt...
