Abstract: An ionic phosphorescent metal complex complex has a formula of [PtM3{(PR″2CH2)3P}(C≡CR)(C≡CR′)(μ—Cl)]2+ An−2/n. M is selected from Au(I) and Ag(I). R, R′ and R″ are identical or different, and are independently selected from alkyl, alkenyl, alkynyl, aryl, and heteroaryl. Each of the alkyl, alkenyl, alkynyl, aryl, and heteroaryl may be substituted with one or more substituents selected from alkyl, alkenyl, alkynyl, alkoxy, amino, halogen, halogenated alkyl, aryl, and heteroaryl. The substituent is optionally further substituted with one or more of the following groups: alkyl, alkenyl, alkynyl, alkoxy, amino, halogen, halogenated alkyl, aryl, and heteroaryl. An− is a monovalent or divalent anion, n is 1 or 2, μ—represents bridging linkage. The organic light-emitting diode prepared by using the complex as the light-emitting layer dopant has an external quantum efficiency of 10% or more, and can be applied to the fields of flat panel display and daily lighting.

Abstract: This disclosure relates to an environmental-friendly and cost-efficient approach to synthesize CsPbBr3 powders in a large scale at room temperature with water. Using ultrasonication and centrifugation, CsPbBr3 nanocrystals can be obtained with green (˜522 nm) and blue (˜493 nm) emissions from the powders. The photoluminescence quantum yield of the blue-emitting nanocrystals is 80%, which is much larger than 61.4% of the CsPbBr3 nanocrystals made by an anti-solvent method. The green-emitting nanocrystals exhibit better stability than those made by the anti-solvent method over a period of 9 days. The method opens a new avenue to potentially produce inorganic and/or inorganic-organic hybrid halide perovskite nanocrystals without harmful organic solvents used in precursor solutions.

Abstract: This disclosure relates to tertiary amine solutions of metal precursors used for chemical vapor deposition or atomic layer deposition. The tertiary amine solutions have many advantages. They dissolve high concentrations of non-polar precursors without reacting with them. They do not supply impurities such as oxygen or halogens to the material being produced, nor do they etch or corrode them. Vaporization rates can be chosen so that the solute and solvent may be evaporated simultaneously, have high flash points, and low flammability. Small droplets may be formed easily which facilitate rapid evaporation without decomposition of he dissolved metal precursor to supply vapors for chemical vapor deposition or atomic layer deposition processes.
