2.4.2. XRD Measurement
X-Ray Diffraction XRD been used for investigation of a crystalline structure such as crystalline order, crystalline orientation and also for estimation of crystalline size material.
The XRD measurement has been carried out by using a diffractometer that based on the reflection method of x-ray radiation. The XRD spectra were performed as diffraction peak
intensity corresponding to the diffraction angle. From the spectra of XRD measurement can be determined the planes distance of the crystal d

In this experiment the XRD measurement has been carried out in the range of diffraction angle: 10-80

2.4.3. UV-VIS measurement
The optical characteristics of Sudan III molecules and PVK in form of solution and film were obtained from UV-VIS measurement. This measurement was carried out using an instrument
of Beckmen DU-7000 Single Beam Spectrophotometer. This measurement obtained UV-VIS spectra in range of 250-800 nm. The background of the sample was first measured. The
solvent used for Sudan III and PVK solution samples were chloroform.
