英文摘要	Spectral adjustment based on the energy transfer process between donor-acceptor pairs has been routinely used to design luminescent materials with different colours and absorption bandwidths. This work reports an alternative way to design new luminescent materials based on a site-selected energy transfer mechanism using high precision control of dopants. The new material Sr2SiO4: Eu2+, Pr3+ has been successfully synthesized to show versatile emissions under site-selected excitation. We demonstrate an efficient site-selected energy transfer process from Eu2+ to Pr3+ and that dual-mode spectral control can be achieved by choosing Eu2+ in Sr2SiO4 as a yellow emission centre and Pr3+ as a red and near infrared emission centre. Therefore a yellow-to-orange phosphor has been realized with excitation-dependent adjustable red and near infrared emissions. The site-selected spectral adjustments and energy transfer mechanism are investigated in detail. This work suggests the design and synthesis of new materials for application in solar cells and white LED devices.; "973'' program [2014CB643801]; National Natural Science Foundation of China [21271191, 20971130, 51272259, 51572232, 51561135015, 51602271]; SCI(E); ARTICLE; 5; 1022-1026; 5
