Diodes and transistors are, without any doubt, among the most impactful innovations that have guided the technological advances in computing and every smart device in the present day. However, the rapid technological growth associated with Industry 4.0 is continuously demanding greater computing power. Despite the incredible advances of lithography techniques over the last decades, they are nearing their physical limits, implying that the development of alternative approaches is critical to meeting the technological demands of the semiconductor industry, as has been stated worldwide. Here, we describe the proof-of-concept of a tunable allphotonic molecular analog based on a Tb3 + /Eu3+ complex embedded into a di-ureasil hybrid host, which responds to light in a manner analogous to the behavior of a conventional electronic transistor. This system permits reversibility, in contrast to conventional electronic components, here a new function requires new circuitry The proposed conceptual analog can, in principle, be applied to other optical centers with faster luminescence dynamics, opening the path toward faster photonic analogs. To the best of our knowledge this is the first example of an all-photonic molecular analog based on trivalent lanthanide luminescence which capable of reproducing then input-output characteristics of a conventional electric transistor.
