Highly emissive copper(i) halide complexes having thermally activated delayed fluorescence (TADF) have been paid much attention. Here, a series of four-coordinate mononuclear copper(i) halide complexes containing both bi- and mono-phosphine ligands, [CuX(dpmt)(PPh3)] (dpmt = 3,4-bis(diphenylphosphino)-2,5-dimethylthiophene, X = I (1), Br (2) and Cl (3)), were synthesized, and their molecular structures and photophysical properties were investigated. These complexes exhibit intense deep blue emission in crystal state at room temperature and have peak wavelengths at 447-460 nm with microsecond lifetimes (τ = 114-752 μs). Emission color can be largely tuned from deep blue to green, from crystal to film state at 293 K. The emission of the complexes 1-3 mainly originates from intraligand and LLCT transitions. Solution-processed, nondoped and doped devices of complex 3 exhibit yellowish green emission with CIE(x, y) of (0.3557, 0.5031). The nondoped device gives a maximum external quantum efficiency (EQE) of 2.47% and a maximum luminance of 316 cd m-2.

We report herein a supramolecular nanoassembly, ca. 30 nm in diameter, consisting of a green fluorescent, β-cyclodextrin-based branched polymer co-encapsulating a red emitting singlet oxygen (1O2) ph...
In the past decade, hydrophobic fluorescent carbon dots (OCDs) have received little attention, and its potential application and light transition mechanism is seldom explored. Here we report a novel o...
It is known that polychromatic carbon quantum dots (CQDs) can be obtained by doping and surface modification. The layer-wise synthesis of blue and green emitting CQDs (with typical sizes between 3 and...
A current issue facing light-emitting devices is a missing suitable material for green emission. To overcome this, we explore semiconductors possessing (i) a deep conduction band minimum (CBM) and sha...
Residential green and blue spaces may be therapeutic for the mental health. However, solid evidence on the linkage between exposure to green and blue spaces and mental health among the elderly in non-...
This is a prospective cohort pilot study. The investigators are planning to develop an original, standardized colorectal anastomosis inspection method, which will systemically inspect the ...
Indocyanine green is a dye, using in surgery to bring out the intraoperative evaluation of tissue perfusion. After intravenous injection of indocyanine green, using a near infrared light,...
The aim of the study is to establish a new and more accurate method to visualize the peritoneal changes caused by endometriosis using Indocyanine Green mediated fluorescence imaging. The h...
A study of non-inferiority design comparing brilliant blue and indocyanine green as intraoperative dye in macular pucker and macular hole.
The goal of this clinical research study is to find lymph nodes before surgery using a dye called indocyanine green (IC-Green). Objectives: 1. To determine the feasibility of usi...
A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.
Unstable isotopes of copper that decay or disintegrate emitting radiation. Cu atoms with atomic weights 58-62, 64, and 66-68 are radioactive copper isotopes.
Protein analogs and derivatives of the Aequorea victoria green fluorescent protein that emit light (FLUORESCENCE) when excited with ULTRAVIOLET RAYS. They are used in REPORTER GENES in doing GENETIC TECHNIQUES. Numerous mutants have been made to emit other colors or be sensitive to pH.
Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.
Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.
