Abstract AR
تم دراسة الخواص الطیفیة (الامتصاصیة و الفلورة) لمزیج الصبغات اللیزریة (رودام ین 6G, رودامین 3GO, و رودامین B).
هذا النوع من الصبغات يعود إلى عائلة الزانثين, حيث تمت إذابتها في الكلوروفورم لتحضير محاليل بتركيز (1*10-5 M) بنسب مختلفو مثل, 1R6G:1R3GO:1RB, 2R6G:1R3GO:1RB, 3R6G:1R3GO:1RB, 4R6G:1R3GO:1RB, 1R6G:2R3GO:1RB, 1R6G:3R3GO:1RB, 1R6G:4R3GO:1RB, 1R6G:1R3GO:2RB, 1R6G:1R3GO:3RB و 1R6G:1R3GO:4RB) و بدرجة حرارة الغرفة.
الكفاءة الكمية المحسوبة للرودامين المذاب في الكلوروفورم باستعمال النسب أعلاه كانت كما يلي (%89, %92, %93, %95, %92, %93, %94, %84, %84 و %84) على التوالي. تم حساب زمن العمر الإشعاعي و كما يلي (0.188, 0.19, 0.203, 0.209, 0.198, 0.196, 0.201, 0.191, 0.207 و 0.219) نانوثانية على التوالي.
كما تم حساب زمن عملا التألق و كما يلي (0.167, 0.174, 0.189, 0.198, 0.182, 0.183, 0.189, 0.160, 0.174 و 0.184) نانوثانية على التوالي.
Abstract EN
The spectral properties (absorption and fluorescence) of laser dyes (Rhodamine6G, Rhodamine 3GO and Rhodamine B) mixture have been studied.
This type of laser dye belongs to the Xanthenes family, it has dissolved in chloroform to prepare (1*10-5 M) in different ratio such as (1R6G:1R3GO:1RB, 2R6G:1R3GO:1RB, 3R6G:1R3GO:1RB, 4R6G:1R3GO:1RB, 1R6G:2R3GO:1RB, 1R6G:3R3GO:1RB, 1R6G:4R3GO:1RB, 1R6G:1R3GO:2RB, 1R6G:1R3GO:3RB, and 1R6G:1R3GO:4RB) at room temperature.
The quantum efficiency of the dissolved Rhodamine in chloroform has been computed by using the above ratio and their results are as follows (89%,92%, 93%,95%,92%,93%,94%,84%,84%,and 84%) respectively.
The Radiative lifetime have been computed as given (0.188,0.19,0.203,0.209,0.198,0.196,0.201,0.191,0.207,and0.219ns)respectively.
Fluorescence lifetime have been also computed as given (0.167,0.174,0.189,0.198,0.182,0.183,0.189,0.160,0.174,and0.184ns) respectively.
