| Abstract: | The ternary system Lanthanide (Ln) N,N bis(2 oxopyrrolidin 1 ylmethyl)glycine (MPG) phenanthroline (phen) has photochromism turning from yellow to green in aqueous solution when irradiated with sunlight or Hg lamp while undergoing a reversible colour change from green to yellow in dark. With excitation spectrum, emission spectrum and UV VIS spectra, its photochromic behavior and the effect of pH on it were investigated. |

| Keywords: | photochromism N N bis(2 oxopyrrolidin 1 ylmethyl)glycine lanthanides ternary complex |
