摘要：
Strong blue emission is observed from Ti-doped MgAl2O4, yellow emission from a Mn-doped one and white light emission from a V-doped one. The optimum condition to obtain the strongest emission was studied by changing the doping density and growing atmosphere. The microscopic models for these emission processes are proposed from observation of other optical responses and electron spin resonance spectra both in the electronic ground and excited states.
