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 beam epitaxy ¹ , 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.
