Abstract: | Rhodamine-6G (Rh-6G) is embedded in sol-gel glass samples which have been prepared by three different methods namely: 1) using
HCl as catalyst and glycerol as Drying Control Chemical Additive (DCCA), 2) using HCl as catalyst at 60 °C and drying at room
temperature and 3) using HCl as catalyst at 60 °C and heated at 600 °C for 3 h. Comparative studies of spectroscopic and lasing
properties of the three types of Rh-6G containing samples were carried out with the lapse of time upto 8 months. Photostability
of Rh-6G containing sol-gel samples is measured in terms of half life under Nitrogen laser pumping as number of pulses of
N2 laser necessary to reduce the dye laser intensity to 50% of the original value and value is 7500 pulses at 1.67 Hz rate.
The best performance of Rh-6G, as far as its spectroscopic and lasing properties are concerned was found in third type of
host matrices using HCl as catalyst at 60 °C and heated at 600 °C for 3 h. |
