Abstract AR
تم في هذا البحث دراسة تأثير الإشابة بالمثيل الأحمر و المثيل الأزرق على طيف الامتصاص و فجوة الطاقة البصرية لأغشية poly(methy1 methacrylat) PMMA.
إذ قيست النفاذية البصرية (T%) ضمن مدة الأطوال الموجية 190-900 للأغشية المرسبة بطريقة القولبة.
أن نتائج الامتصاصية دلت على أن التشويب أدى إلى الانحراف الأحمر و الأزرق في قيمة حافة الامتصاص.
و أظهرت الأغشية انتقالات غير مباشرة مسموحة و قد تأثرت بالأشابة.
حسبت الثوابت البصرية كدالة لنوعية الأشابة مثل معامل الانكسار، معامل الخمود و ثابت العزل بجزئيه الحقيقي و الخيالي.
Abstract EN
The effect of doping by methyl red and methyl blue on the absorption spectra and the optical energy gap of poly (methyl methacrylat) PMMA film have been studied.
The optical transmission (T %) in the wavelength range 190-900 nm for films deposited by using solvent casting method were measured.
The Absorptance data reveals that the doping affected the absorption edge as a red and blue shift in its values.
The films show indirect allowed interband transitions that influenced by the doping.
Optical constants; refractive index, extinction coefficient and real and imaginary part of dielectric constant were calculated and correlated with doping.
