In the present work, a novel n‐UV convertible colour‐tunable emitting phosphor was obtained based on the efficient Ce3+‐Tb3+ energy transfer in the Y10Al2Si3O18N4 host. By properly controlling the ratio of Ce3+/Tb3+, the colour hue of the obtained powder covered the blue and green regions, under excitation of 365 nm. The steady‐state and dynamic‐state luminescence measurement was performed to shed light on the related mechanism, which was justified by the electronic dipole–quadrupole dominating the related energy transfer process. Preliminary studies showed that Y10Al2Si3O18N4:Ce3+,Tb3+ can be promising as an inorganic phosphor for white LED applications.
