Tasks for September 24
Preparation of 10% wt new exfoliated clay films
Completing synthesis of films
Run AA on As samples
To be done at a later date since As lamp was burnt out Measuring fluorescence of Rhodamine dye by filmsNote: the initial concentration of rhodamine was incorrectly labeled as 159μM, actual concentration was 1.9 mM<br.> Solutions were made for 20, 10 and 1 μM R6G by:
Corrections:
10mL of each R6G dye solution were added to the PVA and PVA-Clay glass vials and the glass vials were placed inside a dark drawer to allow the films to soak the fluorescent dye.
