Physicists at the University of Alberta have created a molecular colourant that can emit light in a wider range of colours than any other molecule currently available.
"This material could have many applications ranging from sensors to biological imaging and optical displays, among others," said former Ph.D. student Stephen Lane, who conducted the research under the supervision of physics professor Al Meldrum.
Instance - Imaging - Change - Colour - Conditions
"For instance, in biological imaging, a change of colour can be used to signal specific biochemical conditions or changes in real time."
The molecule, called P4VB, is versatile and easy to adjust to blue, green or red in the visible colour spectrum, depending on its chemical surroundings. In the study, the researchers note that it could offer a wider colour palette for applications including holographic projectors, vehicle headlights and even IMAX screens.
