Organic/polymeric electroluminescence (EL) has attracted much attention because of their potential applications in large-area full-color flat-panel displays. Since the first high performance bilayer organic light-emitting device (OLED) was reported by C. W. Tang in 1987

much progress has been made rapidly in this field. Various novel materials have been synthesized

and many significant devices have been fabricated

and application of OLEDs has been realized in commercial automotive audio system and cellular telephone. However

the efficiency and lifetime of the devices still have to be improved. Developing new type organic light-emitting materials will play an important role on overcoming the current problem. Whereas the choice of materials is very important because it decides directly the OLEDs’ performance. So study on new organic materials is the key to improve light-emitting coefficient and long lifetime. OLEDs were made up of polymer or small molecular compound. However

the polymers are usually spin coated

so it is difficult to avoid pint holes and impurities and their influence on the characteristic of light-emitting devices. The small molecule

Alq

as a typical one

can be vacuum deposited and therefore the films with high purify

high fluorescent efficiency

high crystallizing temperature

stable performance can be achieved

which is important to the fabrication of OLEDs. Whereas it is expected to obtain a compound that has a resemble structure with Alq

excellent stability and luminescence properties. In this paper

a new light-emitting material ZZnqCl

was synthesized; ZZnqCl

thin films were deposited by using thermal deposition technique. Light emitting devices were prepared using ZZnqCl

as light-emitting layer. There has not been any report on this type of compound so far to our knowledge. The details of an experimental study on the deposition process of ZZnqCl

thin films and devices

and their photoelectric properties were given in this paper. It is demonstrated that such films can be deposited by convenient thermal evaporating technique

and a light-emitting devices is prepared successfully. The films were characterized by ultraviolet spectroscopy (UV)

and photoluminescent spectroscopy. Optical absorption and fluorescent spectra of the films were measured. Significant fluorescence was detected and the spectrum was recorded in which two peaks at 406.4

540nm were observed respectively.
