Optical And Thermal Characterization Of The 8-Hydroxyquinoline Derivative Metal Complex Mgcaq4<br>
<br>

<strong>Abstract</strong><br>
Organic light emitting diodes (OLED’S) 
are an  interesting, prospective choice as a source of 
light for applications in large-area flat panel displays. 
Light emitting materials, MgCaq4     has  been 
synthesized by simple precipitation method at room 
temperature and prepared a blended films of MgCaq4 
with  Polystyrene (PS) at  10, 5, 1 wt%. Optical 
absorption, emission and excitation spectra of 
materials and films were measured at room 
temperature.  The synthesized materials  demonstrate 
a bright emission in violet-  green region at 470-520 
nm. Thermal properties of materials are  determined 
by TGA, DTA,  and DSC.  Today, although many 
other light emitting materials are commonly utilized 
in electroluminescence for different purposes, as 
diffuse lighting and thin displays. 
Keywords—  OLEDs,  Electroluminescence, solid 
state lighting.
