Abstract

This paper reports new results arising from the studies of optical interaction in newly demonstrated crystalline organic multiple quantum wells. Recently, these novel materials have been grown by means of organic molecular Ьеаm epitaxy¹, and their excitonic energy levels have been shown to experience a blue shift·as the spatial dimension of the well decreased. The constituent materials were 3,4,9,10 perylenetetracarboxylic dianhydride (PTCDA) as the well and 3,4,7,8 naphthalenetetra- carboxylic dianhydride (NTCDA) as the barrier.
