In the majority of commercial white LED lights, blue chips with yellow emitting phosphor are employed. To obtain white light, Ce3+ phosphor is placed on a blue chip. Despite its commercial success, it has several problems, including the "halo effect," poor colour rendering, and so on. In recent years, significant efforts have been made to increase the performance of LED lighting. These may be divided into two categories: 1> finding a successor for YAG: Ce and 2> enhancing YAG: Ce's performance. The heat behaviour of the conversion phosphor is critical when it is located near the LED chip.
