The International Morse Code is a method to communicate information by a sequence of ON–OFF outputs. A unique and sometime long combination of ON and OFF signals is required to distinguish letters, numerals and to separate each letter and each word. In the present study we synthesized a simple new yttrium 尾-diketonate complex whose photoluminescence intensity is strongly dependent on the excitation input and can be easily tuned. Three of these different optical outputs have been easily “keyed” ON, OFF and as a space for letters and words, thus adding an additional readable output and hence making the Morse Code much more simple and versatile for optical communication.
