Embodiment 1
[0031] Preparation of Mn 1 Cd 6 In 28 S 52 (SH) 4 ·[H + -DBN] 8 ·[H + -PR] 4
[0032] Weigh 80 mg of indium powder, cadmium nitrate (Cd(NO 3 ) 2 4H 2 O) 40 mg, manganese acetate (Mn(Ac) 2 4H 2 (2) 5 milligrams, 120 milligrams of sulfur powders join in the polytetrafluoroethylene reactor liner, then measure piperidine (PR) 1.2 milliliters respectively, 1,8-diazabicycloundec-7-ene ( DBN) 1 ml, water 1 ml was added to the above liner. The solid-liquid mixture was stirred for 30 minutes, and then the lining of the reaction kettle was put into a stainless steel reaction kettle, sealed and heated to 190°C for 3 days. After the reaction kettle was cooled down, ethanol was added to the reaction product for multiple times of ultrasonic treatment until the solution in the upper layer of the sample was clarified, and then dried by suction filtration to obtain a crystalline manganese-doped metal sulfide red phosphor.

Embodiment 2
[0038] Preparation of Mn 1 Zn 6 In 28 S 52 (SH) 4 ·[H + -DBN] 8 ·[H + -PR] 4
[0039] Weigh 80 mg of indium powder, zinc acetate (Zn(Ac) 2 2H 2 O) 40 mg, manganese acetate (Mn(Ac) 2 4H 2 O) 5 milligrams, 120 milligrams of sulfur powders are added in the liner of polytetrafluoroethylene reactor, then measure respectively 1.2 milliliters of piperidine (PR), 1,8-diazabicycloundec-7-ene (DBN ) 1 ml and 1 ml of water were added to the above lining. The solid-liquid mixture was stirred for 30 minutes, and then the lining of the reaction kettle was put into a stainless steel reaction kettle, sealed and heated to 190°C for 3 days. After the reaction kettle was cooled down, ethanol was added to the reaction product, and the solution in the upper layer of the sample was sonicated several times until the solution in the upper layer of the sample was clarified, and dried by suction filtration to obtain a crystalline manganese-doped metal sulfide red phosphor.

Embodiment 3
[0045] Preparation of Mn 7 In 28 S 52 (SH) 4 ·[H + -DBN] 8 ·[H + -PR] 4
[0046] Weigh 80 mg of indium powder, manganese acetate (Mn(Ac) 2 4H 2 (O) 40 milligrams, 120 milligrams of sulfur powders were added in the polytetrafluoroethylene reactor liner, then measured respectively 1.2 milliliters of piperidine (PR), 1,8-diazabicycloundec-7-ene (DBN ) 1 ml and 1 ml of water were added to the above lining. The solid-liquid mixture was stirred for 30 minutes, and then the lining of the reaction kettle was put into a stainless steel reaction kettle, sealed and heated to 190°C for 3 days. After the reaction kettle was cooled down, ethanol was added to the inner lining of the reaction kettle, and the solution in the upper layer of the sample was sonicated several times until the solution in the upper layer of the sample was clarified, and dried by suction filtration to obtain a crystalline manganese-doped metal sulfide red phosphor.
