STRUCTURAL, ELECTERICAL AND OPTICAL PROPERTIES OF SEVEN TYPES OF Eucalyptus

Abstract

Seven

Eucalyptus

species / varieties in the ground of Industrial Research and

Consultancy Center

.

The samples were dried their leaves and grind to be powder using mortar. To

determine their structural and investigate their properties, the

Ray Florescence (

XRF)

and Fourier Transformation Infra Red (FTIR), Ultra Violet (UV) Techniques were

used. XRF results indicated the sample

Seven types of

Eucalyptus

(

E1-E2-E3-E4-E5-E6-E7

) were collected from the

Ministry of Agriculture and Irrigation (plant sector management) and market. The

samples were dried their leaves and grind it to be powder (

E1-E2-E3-E4

) each one of

them contains approximately thirteen elements such as Potassium(K), Calcium(Ca),

Titanium (Ti), Manganese (Mn),Iron(Fe), Nical (Ni),Copper (Cu), Zinc (Zn), lead

(Pb), Bromine (Br), Rubidium (Rb), Strontium (Sr), Zernike (Zr

(

The sample (E-5) contains ten elements

potassium

(K), calcium (Ca), manganese

(Mn), iron (Fe), and copper (Cu), zinc (Zn), lead (Pb) and bromine (Br), Strontium

(Sr),

Yttrium (Y

(

And two samples (

E6 -E7

) containing nine elements potassium ( K) ,calcium (Ca),

manganese (Mn) , iron (Fe), and copper (Cu), zinc(Zn), lead (Pb) and bromine (Br),

Strontium (Sr

. (

All samples containing calcium (Ca), potassium (K) and iron (Fe) at different

Pedigree

.

The result of all sample Calcium has The highest concentration in(E.3) and

the lowest rate concentration in (E.1) The rise in the proportion of

potassium

,

Iron

concentration rises in (E.7,E.1)

Consecutive

,

The rest contain the same ratio

except(E.6

.(

The XRD results showed that (E1-E2-E3-E4-E5-E6-E7) are non crystalline

.

The FTIR spectra showed absorption in the range (2260-2210cm-1),(1650-1580cm-1)

,(1250-1020cm-1) ,(1335-1250 cm-1) ,( 2260-2210 cm-1 ) ( 850-550 cm-1) (690-

515cm-1)(910-665 cm-1), (3500-3200 cm-1) ,(300-2850 cm-1) (3330-3270 cm-1),

(1500-1400 cm-1) . Ultraviolet-visible spectroscopy (UV) shows different range of

wave length for the seven types (215.75 nm , 212.35nm, 209.65nm , 275.5 nm, 207

9

nm, 215.6 nm ,and 235.28 nm ,) and Energy band gaps (4.15ev, 4.64ev,4.90ev,4.9ev,

5ev , 4.8ev, and 3.50ev) respectively (E1-E2-E3-E4-E5-E6-E7
