TECHNOLOGY FOCUS - ELECTRONICS - Preferred Process: In step (d), the nanocrystal particle solution and the molecular precursor solution are mixed in a ratio of 1:1 to 1:15 on a weight to weight basis. In step (e), the coating is performed by a coating technique selected from spin coating, dip coating, roll coating, screen coating, spray coating, spin casting, flow coating, screen printing, ink-jet printing, and drop casting. The annealing (step (f)) involves baking the mixed solution coated on the substrate, and curing and crystallizing the mixed solution. Baking is performed by heating the mixed solution to 50-100degreesC for one second to 5 minutes under a nitrogen atmosphere; curing and crystallization is carried out at 150-600degreesC for 1 to 5 hours under a nitrogen atmosphere.

SPECIFIC COMPOUNDS - Compound of formula (IIa) and (IIIa) is specifically claimed as the precursor (II).    EXAMPLE - Trioctylamine (16 g), oleic acid (2 g) and cadmium oxide (0.4 mmol) were simultaneously placed in a flask equipped with a reflux condenser on a heating mantle. The reactants were stirred while maintaining constant pressure under a nitrogen atmosphere and a reaction temperature of 300degreesC without any temperature gradient. The reaction temperature and stirring speed were maintained until the red cadmium oxide, turned transparent. Sulfur (S) powder was stirred in trioctylphosphine under a nitrogen atmosphere to obtain a transparent solution. The concentration of the sulfur precursor solution was accordingly adjusted to about 0.25 M. The sulfur precursor solution (2.5 ml) was rapidly fed to the cadmium-containing reaction system while maintaining a temperature of 300degreesC and the mixture was allowed to react with stirring for 4 minutes. After completion of the reaction, the heating mantle was removed and ethanol was added to the reaction solution to reduce the reaction temperature to room temperature as rapidly as possible, to quench the reaction. Centrifugation of the cooled reaction solution from the supernatant gave a cadmium sulfide (CdS) precipitate. The precipitate was separated from the supernatant by decantation. The CdS nanoparticle precipitate was dispersed in toluene to provide a 1 wt.% solution of the dispersed CdS nanoparticles having size of 3 nm. Ethanol (30 ml) was added to the toluene ( 10 ml) dispersion of the CdS nanoparticles. The solution was centrifuged to obtain a precipitate. Pyridine (10 ml) was added to the precipitate, and stirred for about 24 hours to obtain a transparent solution. Hexane (10 ml) was added to the solution, followed by centrifugation. The obtained precipitate was weighed, and then pyridine was added in an amount such that the concentration of the precipitate was 2 wt.%. The mixture was stirred to obtain a transparent solution. Pyridine was added to a cluster of Lut2Cd(S(CO)CH3)2 (A1) to prepare a solution having a concentration of 8 wt.%. The pyridine solution (1.5 ml) of the cluster (A1) was mixed with of the CdS nanoparticle solution ( 0.5 ml) to give a mixed solution of the (A1) cluster (6 wt.%) and the CdS nanoparticles (0.5 wt.%). The mixed solution was coated on a silicon substrate, and annealed by heated to 300degreesC for one hour in to form a thin film on the substrate.
